Borderline

Two Undercover Agents Unwittingly Stalk the Same Target.

A classic film noir crime thriller built on mistaken identity and cross-purposes, where two undercover operatives unknowingly pursue the same target across the US-Mexico border.

The Los Angeles police know that Pete Ritchie has been bringing drugs into the city, but they can't pin a single piece of evidence on him. After many botched attempts to get at the crook, they resort to having cop Madeleine go undercover and seduce her way into Ritchie's circle. Before she can get anywhere, she's abducted by Johnny, a government agent posing as a thug. But Johnny and Madeleine have no idea they're on the same side of the law.
