Heat Lightning

Olga (Aline MacMahon) runs a hotel and gas station in the desert with her younger sister, Myra (Ann Dvorak). Olga tries to look out for the naive Myra, especially regarding her boyfriend (Theodore Newton), whom Olga doesn't like. One night, Olga sees an old love, a thief now named George (Preston Foster), on the run with his partner, Jeff (Lyle Talbot). Although Olga still cares for him, she is also suspicious about his intentions, especially since there are valuable jewels locked in her safe.
