When drug dealer Mickey (guest star Ethan Embry) mysteriously collapses while negotiating a sale, his partner-in-crime, Eddie (guest star Nick Chinlund), accompanies him to Princeton Plainsboro for treatment. But with a major deal pending, Mickey is not forthcoming with the necessary personal information the team needs to treat him. As Mickey's condition worsens, the team resorts to old-fashioned detective work to solve the case. Meanwhile, House and Wilson compete for the affection of a new neighbor, and Chase, Thirteen and Taub attempt to play a practical joke on Foreman.
