Borderline is an American 1950 film noir crime film starring Fred MacMurray and Claire Trevor. Pete Ritchie (Raymond Burr) runs a narcotic drug smuggling operation from Mexico to the United States, which the Los Angeles Police Department and the US federal government have tried to unsuccessfully stop. Since Ritchie's operating procedures are so good, the US authorities haven't even been able to find out the identities of his sources and need a breakthrough. Madeleine Haley (Claire Trevor), and LAPD officer and former OSS operative, is sent undercover to Mexico to charm her way into Ritchie's confidence. Once in Mexico Haley (Claire Trevor) manages to establish contact with Ritchie's gang, but is kidnapped by Johnny Macklin (Fred MacMurray), a federal agent posing as a hoodlum working for a rival of Ritchie's and who also steals a load of Ritchie's narcotics. Haley plays along and joins Macklin on a smuggling trip for the stolen narcotics, with Ritchie in hot pursuit. Fast action movie with lots of surprises. One film noir crime movie you won't want to miss.
