A female cop goes undercover in a high price whorehouse to find a murderer and discovers she likes the assignment more than she should.

The alien criminal from the first movie is dead, but he left a few eggs which are hatching now. The good alien, who still inhabits Tom Beck's body, has been waiting just in case this happened. Unfortunately, his presence in the body has taken a terrible toll on it, draining it of life energy. Additionally relations with Beck's daughter Juliet (now a cop) have deteriorated. But when the killing starts again, they will need to work together to stop the new generation of aliens.
