Phil of the Future is about the Diffy family, a group of time travelers from the year 2121 who traveled back in time using a rented time machine on vacation, though the machine was damaged when Phil used it for personal means on their last stop in the early twenty-first century, leaving them trapped in this barbaric time period (in comparison with the twenty-second century).

The family consists of Lloyd, who is convinced that he’ll fix the time machine in no time, though it’s been quite a while since he made that claim; Barbara, who considers herself a pioneer, as she can (and has) easily adapt to the century she’s living in; Pim, a rebellious girl who dreams of ruling the world and looks down upon the residents of the twenty-first century; and finally the show’s star, Phil, who is much like his mother in adapting to the twenty-first century, though that’s mostly due to him using his futuristic gadgets to get him (in and) out of trouble.

Phil hangs out with Keely Teslow, who dreams of becoming a famous news reporter, though she’s an accomplished singer, as well. Phil and Keely seem to be attracted towards one another, and have gone on a few dates, though nothing exclusively. Keely is also the only person who knows that the Diffys are from the future.

The Diffys regularly must hide the fact that they are from the future, as if they are discovered to be time travelers, they fear they will be taken away by the government. Pim and Phil’s vice principal, Mr. Hackett, believes that the Diffys are aliens of some sort, and has found evidence to support his theory, though something always occurs which leaves him without the knowledge of this evidence.

"Meet a boy named Phil and his family
On vacation from the twenty-second century
They got a rented time-machine and they're on their way
To a time way, way, way back in the day

So now he's Phil , Phil, Phil of the Future
Keeping it together just as best as he can
Phil, Phil, Phil of the Future
He's a twenty-second century man
(A twenty-second century man)

On a holiday through history
But the final destination was a mystery
But something on the time-machine had blown
So they ended up right here in our time-zone

So now he's Phil, Phil, Phil of the Future,
Never knew in history just where he would land
Phil, Phil, Phil of the Future
He's a twenty-second century man
(A twenty-second century man)
Phil, Phil, Phil of the Future
He's a twenty-second century man
(A twenty-second century man)"
