Car 54, Where Are You? (1961)

S02E16 The White Elephant

A group of criminals acquires a haunted diner adjacent to the bank, planning to tunnel through the shared wall and access the vault. However, the officers from the 53rd precinct drop in to check on their progress. Instead of thwarting their plans, they end up assisting the gang in transforming the space into a bustling luncheonette.
