On his first burglary, young locksmith Johnny Ryan (Spencer Teakle) joins old-timer Sam (Arthur Hewlett) on a raid on a jeweller’s shop and grabs £60,000 worth of diamonds.
While making a getaway, the pair are attacked by Al (Alan Edwards) and Ted (Larry Burns), thugs in the employ of shady nightclub owner Ricky Barnes (Martin Benson).
Sam is killed, but Johnny escapes with the stones and seeks refuge in a clip-joint run by tough blonde Mary Weldon (Dorinda Stevens). She plans to collar half the loot, but Johnny, accompanied by Mary’s innocent sister Jean (Felicity Young) heads for a farm to hide out.
The pair are pursued by Ricky, Ted, Mary, and Johnny’s two-timing singer girlfriend, Sylvia (Dawn Brooks). There is a gun battle and the police arrive and pick up Ricky who has been outwitted by the now chastened Johnny.
The film quickly gets down to brass tacks and vigorously plays crook against crook in nightclubs and sleazy apartments until virtue triumphs over vice.
Spencer Teakle effectively fashions his portrayal on American lines as Johnny, Felicity Young makes an appealing Jean, and Martin Benson is in his element as Ricky.
