Jake introduces himself in the opening narration. He has lived more than 4,100 days, and hasn’t spoken a word in 11 years. According to him, there is nothing called chaos as we understand it. Everything follows a pattern. Martin is at the airport, when his colleague hands him the cell phones that passengers have left behind. Martin is about to take all of them to his gifted son Jake, who loves to take them apart. Just as he carries them through a corridor, one of the passengers calls up his lost cell from Mumbai, trying to find where his phone might be. Martin explains he is not stealing it. It was found in the lost items box at JFK, and he works there. Martin is reluctant to send the phone to him when he insists to see his daughter’s picture in it. However, just as he is about to note the address to send it, his own phone buzzes. Jake has done it again, and Martin runs leaving the lost phone on the luggage belt.
When he arrives at his son’s special school, the cops are there because Jake has climbed a tower, and refuses to get down from there. He is busy with his numbers notebook, and won’t let anyone touch him. Martin’s not going up because he is afraid of heights, but manages to persuade him by showing one of the cell phones he’s got for him. Later, as Martin sits Jake in the back seat and is waiting for gas, he notices how distinctly quiet is Jake, compared to the other kids at school. However, he soon finds Jake has got off, and is walking towards the school bus. He notes down something from the back of the bus, but Martin is yet to make out what’s happening. He hopes Jake will cheer up if he gets an orange soda. When they get to the store, Jake notices the gas man has a lottery ticket. Before long, he grabs it runs back into the car and locks it from inside. He notes down the number, as Martin and the store man are getting desperate to take the lottery ticket back. However, when Jake finishes, he gives it back. Livid, the store man tells Martin, he should put that kid in a cage, and when Martin confronts him, the man punches him hard in the stomach.
Later that night at Dublin Island, Kayla Graham is singing at a bar, and her call center manager is filming her performance on the phone that the passenger to Mumbai lost at JFK. After the performance, Kayla doesn’t think she can ever be a megastar. She only sees herself working two cubicles down from her manager. However, he thinks different. He is sure Kayla is destined to be a megastar. After she leaves, the manager drops the cell phone in a passenger bag, which belongs to someone who is on his way to Tokyo. Back at Martin’s place, the alarm goes off at 3:18 am, and Jake completes his number crunching, and is off to sleep. Before long, all the cell phones that he procured from the airport, start ringing together. And more strangely, all the calls are coming from the same number. Oddly enough for Martin, the number is the one that Jake noted from the lottery ticket he found at the gas station.
Meanwhile at a home in Baghdad, a young boy is drooling over Chris Rock on the television, but his mother thinks he is being an idiot. He tries to convince his mom he will make a fortune being a comedian. And they don’t have to make a living by selling bread every day. Sadly enough, their oven doesn’t work anymore, and his mother can’t see his dad crying. They are about to lose their house, and what’s worse – they don’t have any money left. When social worker Clea arrives at Martin’s place, she complains how little he has been able to do with his career. He may have provided for Jake for the last 10 years, but only with decreasing entitlements. That is not helping. Clea tries making friends with Jake, but hardly does she get him to look at her, or even respond. She notices he is intense and quiet, but has to convince Martin that Jake should be in a district care facility. Martin is livid that she thinks him to be inadequate as a dad, but he is not to blame. No one is judging him.
The man from the gas station, Randy, ends up winning the lottery. He hears the announcement on television, and calls home to say he is getting back. Meanwhile, the man with the lost cell phone calls his wife as he is about to leave for Tokyo. He hopes to be back for his daughter’s birthday, but his wife, sitting alone in the daughter’s bedroom sheds a tear, thinking he won’t be able to get back on time. In Afghanistan, the boy meets his friend, who apparently jokes he should join a terrorist recruitment camp to get his oven back. Or he has to steal one. After all, it costs nearly a billion dinars. Does his friend know where he is talking about stealing it from? It is a restaurant where terrorists hang out. And does he know what they do to thieves? The cut their hands and throw them into town square. Meanwhile in Tokyo, hookers are busy thinking about making a fan club under the Kayla Graham brand.
Martin takes Jake to the special facility. However, he is still not responding. He does not seem to be worried about staying at the facility, and leaves with Clea when it’s time. Later, Martin goes to his wife’s grave, and asks her to forgive him for giving up Jake, because can’t forgive himself. Suddenly he notices something lying beside the headstone. It is a federal badge numbered 318. At work, Martin cannot stop thinking Jake has been trying to communicate something. He looks up the internet, and finds an address of the Teller Institute. The website talks about children like Jake. When Martin gets to the address, Professor Arthur DeWitt opens his door. It’s a simple house, and Martin thinks he’s got it wrong. However, when DeWitt asks if his kid has been climbing towers, Martin knows he has come to the right place. Before long, Martin discovers his son is special. He is one of those people like Fibonacci. It’s Greek to Martin, but DeWitt gives him a book on the Fibonacci series. Everything in the universe is based on the series. DeWitt tells him Jake knows the past, the present and the future.
Back at the facility, when Clea sits with Jake, he lays down a bowl of popcorns, and arranges them in a series. It is only to denote a phone number and Clea is shocked to see it is her mother’s. Right then, the same number calls Clea, but no one answers. She is now beginning to see what Martin was saying. Jake gets up, and marks number 18 on the March calendar. Before long, Clea tells Martin about it, and he knows immediately something is about to happen on the date. They only have 22 minutes left for 3:18 to strike, and he is quick to figure out the location is the Grand Central. When the two get there, Martin is waiting at a public phone for a user to finish. It is already 3:17, and the user will not let go of the phone. When Martin gets aggressive, he finds out it is the same man from the gas station, and returns a blow. Before long, the cops stop the fight, and have them grounded. All this happens between on the 19th minute past 3pm. Meanwhile at Baghdad, the two boys enter the restaurant to steal the oven. However, they soon get caught, but the friend escapes. The owners have the lost phone – this time from a passenger who lost it in Kuwait. They hold him down, and ask what he’s doing there. He explains he needs an oven for his family, but he doesn’t want to steal. They tell him it is expensive, so how is he planning to pay up?
After a series of coincidences, that Martin finds out with time, and mainly regarding the man from the gas station, and everything he has done to save school bus number 318, he is astounded yet again. Meanwhile, the original owner of the cell phone calls up Kayla’s call center. She at first is reluctant to help, but she tracks down the phone to Afghanistan. Before she has done that, the desperate man looking for his daughter’s picture, finds it on the billboard. He even gets to look at the lost videos on the big screen. However, Kayla learns from the person who picks up the phone, that it is the young boy about to blow himself up so that his family can buy an oven. The about to be terrorist act is terminated when Kayla promises she can get him an oven.
Meanwhile, Martin runs to Clea’s facility, and is shocked to find out Jake’s gone. Clea has been looking for him as well. Back in Afghanistan the young boy gets and oven, and his mother is proud of him. Martin and Clea find Jake on the tower, and when he manages to climb it, he doesn’t know if Jake is listening to him, or if he understands what he is saying. But he does understand what he is communicating. Jake looks at him, and gives him a hug – probably for the first time!
