Confession, released in the United States as The Deadliest Sin, is a 1955 British second feature ('B')[2]drama film directed and written by Ken Hughes and starring Sydney Chaplin, Audrey Dalton and John Bentley.

Louise shows Mike to his old room where, alone, he unlocks his suitcase and reveals a secret compartment full of dollar bills and a gun.

Alan is Roman Catholic and decides to confess his crime (shown in the opening scene).

The police compare the bullets and (wrongly) decide that both victims were killed by the same man.

They ask the priest to go about his work as usual, and they will watch him, in case the murderer comes after him, to which he agrees.

The police set a trap by telling the family untruthfully that the priest has obtained permission from Rome to make a statement the next morning about Alan's confession.

Mike climbs to the bell tower, firing at the police, but runs out of bullets.

[5] The Monthly Film Bulletin wrote: "This is an average melodrama, technically quite competent, but the situation is scarcely developed and little depth is given to any of the characters.

The slow pace makes for a slackening of tension, and the contrived story loses its grip some time before the over-predictable dénouement.

"[6] Kine Weekly wrote: "Exciting and unusual crime melodrama ... Its box-office Anglo-American cast and experienced director make the most of the provocative and gripping plot, and the by-play is both touching and apposite.
