Something is seducing and killing young men, and the Special Unit 2 Squad suspects a young woman of being a 'spider mutant' link. A young girl is also attacked by the creature and is taken under the wing of O'Malley, who finds he has a growing attraction to the girl. Ultimately they discover that there are more of these beautiful and deadly 'black widows' than they anticipated and they must find the nest before they claim more victims.
