involved drug dealers. Need Help!? I am trying to find out the name of a movie that I can only remember sparely. It had a man who resembled Chevy Chase, but I have a feeling it wasn't, and a blonde model. It was from the 80s around that time. The plot was about a man who was an undercover cop in some sort of island resort and he had the blonde girl and an old man to help him. He tried to infiltrate a drug cartel family and he was pretending to be a rich drug dealer himself. In one scene they attack the house he is staying while he is with the blonde model.

I cannot remember anymore, and I am sorry if this isn't enough to help. Please help me find the name of the movie, for it is starting to bug me!!

Thank you all in advance.
