Josh Futturman feels stuck in his dead-end job as a janitor so all he really does is play Biotic Wars, an unbeatable videogame the rest of the world has given up on. But when Josh beats the game, mysterious visitors from the future appear: the world is in danger, and Josh is the only one who can save it.

In 1969, Josh, Tiger and Wolf launch a mission to infiltrate a fraternity party and prevent Dr. Kronish from contracting herpes—but the destruction they’ve left in their wake quickly catches up with them.

Tiger and Wolf decide it’s time for Dr. Kronish to die. Josh reluctantly agrees to help—but when he realizes he can’t go through with it, he finds himself caught in Tiger and Wolf’s sights instead.

In the wake of the disastrous attempt to assassinate Dr. Kronish, Tiger and Wolf kick Josh off the mission. When they realize their Time Travel Device (TTD) is compromised, Josh makes a deal: if he can get them more fuel, they’ll let him back on the team.

Tiger, Wolf and Josh work to unmask the Biotics undercover at the Kronish Labs Christmas party. Meanwhile, Josh grows closer to his coworker Jeri as she helps him avoid the obsessed policeman hot on Josh’s tail.

With just twenty-seven minutes before a bomb explodes in the head of their captured Biotic, Josh, Tiger, and Wolf hold a high-stakes interrogation in Josh's bedroom while Josh’s unwitting parents host a holiday dinner party downstairs.
