L.A. Heat

A van filled with illegal Mexican immigrants crashes in a violent explosion, killing many of its stowaways, and Chase and August arrive on the scene. Survivors limp with cuts and bruises, but the smuggler, the Coyote, has disappeared. One of the survivors tells the detectives that a man named Delgado had smuggled them across the border. Det. Maria Vallejo connects Delgado to a suspected sweatshop owner, and the detectives reluctantly put her undercover.
