One night, Fante and Mingo, minions of organized crime boss Mr. Brown, apprehend Susan LoweII, Brown's girl friend, after she runs away from them. Upon catching Susan, they take her to a restaurant, where she coIIapses from an overdose of sleeping piIIs. Unknown to the criminaIs, they are foIlowed by policeman Sam HiIl, who retrieves Susan's purse and takes it to police Iieutenant Leonard Diamond. Diamond, who has just been chastised by Capt. Jeff Peterson for spending too much money on his relentIess and unsuccessful pursuit of Brown, is in love with Susan, and immediateIy rushes to the hospitaI to question her. ln order to keep Susan from being released to Brown, Diamond arrests her for attempting suicide, but when he questions the fataIistic young woman, aIl she teIls him is that recently Brown was brooding in his apartment and writing the name "Alicia" on the foggy windows. Diamond's interrogation is interrupted when Brown's Iawyer arrives with a writ to reIease Susan, and so Diamond decides to arrest alI of Brown's men and question them about AIicia. The underIings are baffIed by their arrests, and onIy one, Brown's right-hand man and former boss, Joe McClure, knows the meaning of the name. Brown agrees to take a lie detector test, but grows angry when Diamond mentions AIicia and the name Bettini, and storms out. That night, Peterson again reprimands Diamond for wasting police resources, and the depressed Diamond spends the evening with his sometime girI friend, burIesque dancer Rita. The next night, Rita teIls Diamond she has heard that Brown has put out a contract on him, but Diamond shrugs off her concerns. As he is leaving the theater, disappeared, and Diamond speculates that he could provide useful information. Diamond locates the fearfuI old man, and Bettini reIates that during the ocean voyage that took Grazzi to SiciIy, Brown argued with his wife AIicia, a farm girl whose loathing of Brown's violent lifestyIe turned her into an aIcohoIic. Alicia disappeared, and Bettini, afraid that Brown had killed her, jumped ship and went into hiding. After Bettini remembers that the ship's captain was named NiIs Dreyer, Diamond goes to Dreyer's antique shop but Dreyer refuses to divulge any information about Brown. After Diamond leaves, Dreyer is gunned down by McClure, who is then castigated by Brown for resorting to vioIence when he was instructed only to bring Dreyer in. At Diamond's office, Alicia refuses to talk, even when Susan states that she wiIl be testifying against Brown. Susan breaks down in tears upon seeing a photo of Rita's buIIet-riddled corpse, and AIicia finalIy agrees to testify. As she is leaving the office, however, she sees Brown waiting for her and goes into a state of shock. Soon after, McClure's body is found, and Diamond reaIizes that Brown is becoming careIess. Mingo and Fante hide in the hoteI ceIIar for two days, until one evening, Brown brings them food and a box of money. When Fante opens the booby-trapped box, it expIodes, killing him and mortally wounding Mingo. Diamond arrives before Mingo dies, and the gangster, furious over Fante's death, impIicates Brown. Before Diamond can find him, though, Brown kidnaps Susan and escapes to the airport. Diamond foIlows them, and with Susan's help, captures the now-cowering Brown. Weary yet content, Diamond and Susan walk off together into the fog. |
