Ben Healy and his social climbing wife Flo adopt fun-loving seven year old Junior. But they soon discover he's a little monster as he turns a camping trip, a birthday party and even a baseball game into comic nightmares.
In a violent, near-apocalyptic Detroit, evil corporation Omni Consumer Products wins a contract from the city government to privatize the police force. To test their crime-eradicating cyborgs, the company leads street cop Alex Murphy into an armed confrontation with crime lord Boddicker so they can use his body to support their untested RoboCop prototype. But when RoboCop learns of the company's nefarious plans, he turns on his masters.
