Police Squad!: A Substantial Gift (The Broken Promise)

Sally, a bank teller deeply in debt, robs her own bank and plants evidence that implicates a fairly commonplace man who was present during the crime. Police Squad, a special unit of the police force, is called to investigate a double shooting that happened during the robbery. However, the stories just don't add up. The evidence builds and points in Sally's direction, but it's up to Frank to find the clues that will put her away.
