When a woman is found dead with a bottle of pills that are lab trial samples, Lassiter and Gus, who are taking the same tap class, team up to dance their way to catching a murderer.

Shawn and Gus show up at a crime scene at a swanky mansion where a young bachelor, Lance, just fell to his death. Lassie doesn't believe it was murder, but Shawn thinks otherwise. He notices that Lance's ankles and arms were not broken, causing him to believe that he didn't try to brace his fall and was therefore dead before his body touched ground.
