Synopsis by Hal Erickson
Hal Fletcher plays a pilot with in-law trouble. Lustily wed to Sharyn Tabert, Fletcher enters into a menage a trois when Sharyn's stepsister makes the scene. Romance leads to disaster as Fletcher becomes involved in a murder scheme hatched by the two ladies. It soon becomes clear that no one can be trusted, and that no relationship is sacred. The R-rated Stepsisters seems to always be in a hurry, as if the filmmakers were about to run out of film at any moment.
