AllMovie

Released in English-speaking countries as One Bullet is Enough, this Franco-Spanish co-production is a bizarre blend of music, comedy and crime melodrama. Famed European singer-impressionist Georges Ulmer stars as Carmo, a small-time pickpocket who is framed for a big-time murder. While behind bars, Carmo mends his ways, but he may not live long enough to reform on the "outside." Meanwhile, his faithful girlfriend Florence (Vera Norman) works day and night to prove Carmo's innocence and nail the real killers. In some markets, Une Balle Suffit... was misleadingly advertised as a "straight" gangster flick.
