Miami, Valentine's Day. The main character, a womanizer, meets a girl he really likes in a store, and, overcome with desire, wants to spend the evening with her. But here's the catch: she is married and afraid of her Cuban husband.

Detectives Marcus Burnett and Mike Lowrey of the Miami Narcotics Task Force are tasked with stopping the flow of the drug Ecstasy into Miami. They track the drugs to the whacked-out Cuban drug lord Johnny Tapia, who is also involved in a bloody war with Russian and Haitian mobsters. If that isn't bad enough, there's tension between the two detectives when Marcus discovers that playboy Mike is secretly romancing Marcus’ sister, Syd.
