When LAX receives a word from Homeland Security that a credible threat has put the airport on high alert, Harley and Roger debate over whether to notify the public or continue to keep the news a secret. Tensions build when passengers are faced with longer lines due to extra security, and Roger puts his relationship with his daughter in jeopardy when he refuses to let her fly -- forcing her to miss a very important recital. Meanwhile, Tony must take care of a senile old woman who has been left stranded at the airport by her son who can no longer bear the burden of taking care of her.
