Borderline
A federal agent (Fred MacMurray) and a government investigator (Claire Trevor) infiltrate a Mexican drug-smuggling operation, only to find themselves both chasing the same cartel and questioning each other’s motives. Disguises, double-crosses, and close calls keep them guessing – and falling for each other – as they try to bring down a ruthless kingpin (Raymond Burr). Directed by William A. Seiter, the film balances suspense and romance against an atmospheric borderlands backdrop, showcasing the star power of its leads and a noirish crime story with unexpected twists.
