A runaway truck containing the corpse of a slain gang leader rolls into a California nightclub owned by Johnny Cain, a hard bitten former free-lance adventurer. The gang threatens to kill Johnny, unless he solves the murder. The CIA also investigates - because it turns out that the slaying was part of a long-range Communist plan to take over the crime syndicate. Cain's search for clues leads him into a maze of beautiful girls, mysterious Oriental statues and murderous spies. Written by alfiehitchie

A Very Intricate Plot
29 July 2013 | by Uriah43See all my reviews

A beautiful Asian woman named "Revel Drew" (Nancy Kwan) is sitting at a table in a restaurant with a man who happens to be the head of all of the illegal operations on the West Coast. Not long afterward, as Revel gets up to talk to the piano player named "Lucky Jones" (Buddy Greco) a large truck comes crashing through the wall opposite of where Revel was sitting only minutes before and kills the mob boss. The owner of the restaurant is "Johnny Cain" (Adam West) who just happens to be a retired assassin and a former lover of Revel. Because of the suspicious nature of the murder, he immediately becomes a suspect and a contract is placed upon his head if he cannot exonerate himself. He has 72 hours. Anyway, rather than divulge the entire story and possibly ruin the mystery and suspense, I will just say that this film has a very intricate plot which requires close attention to detail. While the acting wasn't great and the dialogue seemed a bit stiff at times, I thought this was a pretty enjoyable film all the same. Adam West performed in an adequate manner as did Nancy Kwan who still manages to look quite attractive several years after her starring role in "The World of Suzie Wong". It's definitely dated but all things considered I rate this as slightly above average.
