A man's brother dies of an overdose from a new and potent drug introduced by a drug gang. He puts off his wedding to a beautiful model and postpones taking over the family business while he travels to Hong Kong to learn Tiger Claw kung fu from its master. Then he plans to take his revenge on the drug dealers responsible for his brother's death.

A new batch of recruits arrives at Police Academy, this time a group of civilian volunteers who have joined Commandant Lassard's new Citizens on Patrol program. Although the community relations project has strong governmental support, a disgusted Captain Harris is determined to see it fail.
