Hospital shop steward Lenny Moss is pulled into a new murder investigation when a practical joke he initiated backfires. A beautiful pharmaceutical sales rep has been found murdered in the hospital, and Lenny and his co-workers are implicated. His only chance of saving them all from termination is to organize the workers to find the killer. Suspicions fall on an ego-maniacal transplant surgeon demanding a million dollars for an unproven procedure and on a GI physician involved in a suspicious drug study. Meanwhile, a brutal heat wave is sending laundry workers to the Emergency Room with heat stroke, but the administration resists Lenny's demand that they cool the laundry down. With emotions and bodies heating up, Lenny finds himself boxed in a dangerous corner with no way out but for the help of his many friends throughout the hospital.
