A beloved parish priest is knifed in an alley in San Francisco. Motorcycle cop Tony Curtis asked to be transferred so he can investigate; the priest had been a tremendous influence on him at the orphanage. He's turned down. At the funeral he spots Gilbert Roland - harboring the unfortunate name of 'Malatesta' - and has a hunch. His superiors put him on leave, and he gets on Roland's good side, moves into his home, and falls in love with with Roland's cousin, Marisa Pavan, while trying to find some reason to confirm his suspicion.
It's clearly a Tony Curtis vehicle, but as soon as Roland steps onto the screen, he pushes The star off. In fact, the only way for anyone else to get their time on. Screen is to have Roland someplace else. He's big, he's boisterous, he's good-hearted, and loves everyone, particularly the dead parish priest. What a mistake for any actor to agree to be in a movie with him!
Besides Gilbert Roland, this movie features some nice location shooting in San Francisco, which is completely recognizable, despite never showing the Golden Gate Bridge, cablecars, Union Square or the Transamericabuilding (that last had not been built yet).
