A thief (Snider) is tricked into a cruel scheme to steal precious jewellery from an elderly woman by Mr Williams. Something goes wrong with the heist, and Snyder is caught and sent to prison. Mr Williams who has the ring, gives it to Snyders wife, with whom he is having an affair. An Albany Cine Club production from 1981.

A group has gathered outside a court house, where a police officer fends off their questions. The accused leaves the court and climbs into a car with his wife. The title 'All for a Ruby' appears. The woman swims in a pool before sitting with the man by the water while he reads the newspaper. A headline reads 'Jury clears Snider at jewel theft trial'. A Butler pours the couple drinks at the table, before the telephone rings. A Mr. Williams is on the other end of the line. 'You had a close shave by all accounts,' he says, before inviting him over to talk about a scheme he might be interested in. They plot to steal from an old lady. He opens a safe, hidden behind a painting, bringing out a ruby ring, worth a hundred grand. 'You gotta lift that little gem... then I sell it.' 'It's a deal,' replies Snider, but the robbery goes wrong. A voice is heard; 'You have been found guilty of theft... I sentence you to three years imprisonment.' Williams arrives at Snider's residence, where he gives the ring to Snyders' wife, whom he is secretly having an affair.
