Synopsis:
After being captured by the police forces of the future, Slam and Shorty are taken to medical facilities. Shorty is restored to life, but the ruler orders them both killed when Slam refuses to reveal the location of their time machine. The detectives face Iron Fingers, a gladiator and assassin. They use acid to defeat him and make their escape.

The three criminals whom they met earlier help Slam and Shorty escape the city. Then the crooks try to steal the time machine. Professor Kenton returns in time to interrupt the theft. Slam, Shorty, and the Professor then use the time machine to return to their own time safely.
