[2][3][4] After being released from prison, where he had served 6 months for car theft, the young Floyd Gambino and the older Joe rob a jewelry store.

Due to a minor accident, Floyd, who is carrying the loot worth half a million, has to take a room in a motel.

Its owner Fred Norton and his wife Michelle get behind the true identity of their guest and prevent his discovery.

After a night of love with Michelle, the diamonds have disappeared and remain untraceable.

Joe takes up the pursuit of the bus and kills Michelle, but can not find the gems with her.
