Somebody's ripping off rap artist Randy Rand by counterfeiting copies of his hottest tunes and cutting in on his profits. For Frank and Joe, the case is a piece of cake. The trail leads right to a hustler named Jack Martinelli, and the Hardys catch the con man in the act. But he act turns downright dirty when Martinelli turns up dead.

Suddenly rapster Randy faces a murder rap -- and the Hardy boys face deadly danger on the mean streets of New York. They're convinced the real killer is running free, and it's up to them to do their stuff -- no matter how rough it gets. Because if they don't find the dude who did the deed, cool man Randy Rand will soon be cooling his heels in jail!
