When Tom's hit by a trolley while he and Jerry are investigating their latest case, he's sent to recover at the local animal hospital. But a detective is never off the case! Tom begins to suspect the answer to the case they're working on is right under his broken nose. Problem is, he's in traction and can't move. That's okay, he's got a partner in crime-solving - Doc Jerry makes the rounds at the animal hospital and solves the mystery, but not before sending Tom on the rounds to endure various tests (e.g. x-rays, stress test, physical therapy, etc…) and to do some investigating of his own.
