Myra and Ellie Thomas, sisters residing in Glendora, California, find themselves entangled with their abusive stepfather, Charley, who was once married to their now-deceased mother, Bonnie. When Charley attempts to rape the younger Myra, Ellie intervenes, shooting him with a shotgun. Instead of reporting the incident to the authorities, the sisters decide to escape to Los Angeles, seeking refuge with their only known relative, a wealthy uncle named Ben Siemen.
Unbeknownst to Ellie, her uncle quickly involves her in a money-laundering operation. However, upon discovering the illicit scheme, Ellie double-crosses her uncle and escapes with the money. She then instructs Myra to rendezvous with her in El Paso, Texas, as they plan to flee the country. A series of unfortunate deaths follows as the uncle and his hired hitmen relentlessly pursue the sisters to recover the stolen funds.[2]
