24 meets the X Files in the biggest teen blockbuster of the summer...

STOP THE COUNTDOWN. SAVE THE WORLD...

Leaving the beach, seventeen-year-old Janelle Tenner is hit head on by a pickup truck.

And killed.

Then Ben Michaels, resident stoner, is leaning over her. And even though it isn't possible, she knows Ben somehow brought her back to life...

Meanwhile, Janelle's father, a special agent for the FBI, starts working on a case that seems strangely connected to Ben. Digging in his files, Janelle finds a mysterious device - one that seems to be counting down to something that will happen in 23 days and 10 hours time.

That something? It might just be the end of the world. And if Janelle wants to stop it, she's going to need to uncover Ben's secrets - and keep from falling in love with him in the process...
