Janitor Josh Futturman feels stuck in his dad-end job so he spends a lot of time playing unbeatable video game "Biotic Wars"; after he beats the game, mysterious visitors from the future appear, endangering the world -- and only Josh 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 catches up with them.

When Tiger and Wolf decide it's time for Dr. Kronish to die, Josh reluctantly agrees to help but ultimately finds himself caught in Tiger and Wolf's sights after realizing he can't go through with it.

Following the disastrous assassination attempt on Dr. Kronish, Tiger and Wolf kick Josh off the mission; when their Time Travel Device is compromised, Josh agrees to try to get them more fuel if they let him back on the team.

Tiger, Wolf and Josh work to unmask the Biotics undercover at the Kronish Labs Christmas party; Josh grows closer to co-worker Jeri as she helps him avoid the obsessed policeman hot on his trail.

With 27 minutes before a bomb explodes in the head of the captured Biotic, Josh, Tiger and Wolf hold a high-stakes interrogation in Josh's bedroom while his unwitting parents host a holiday dinner party downstairs.
