Mara (Rita Hayworth) is the lonely owner of a gas station on a remote road leading to Salina, Mexico in this psychodrama. A young hippie (Robert Walker Jr.) is mistaken for her son who had left four years earlier. He is encouraged to stay and develops an amorous relationship with his supposed sister Billie (Mimsey Farmer). He looks into the family history and discovers Billie may have killed her own brother and Mara could very well be covering up the crime. Warren (Ed Begley) and Mara dance the frug in this feature, the last for Begley who died in April, 1970 and the second to last film for legendary screen siren Hayworth.
