Off Again, On Again(1945)

Good samaritan Shemp rescues a girl from an accident, and a newspaper photographer snaps a picture of her thanking Shemp. The paper mixes up the caption, implying that Shemp and the girl are lovers. This doesn't sit well with Shemp's fiancee, who breaks off their engagement, leaving him so heartbroken he asks the rescued girl's gangster boyfriend (Dick Curtis) to kill him. When Shemp's intended returns and apologizes, he realizes that his days are numbered unless he can find the gangster and call off the hit.
