The Gypsy Moths (1969)

On a 4th of July weekend, three barnstorming skydivers arrive to perform in a small Kansas town. They are hosted by the youngest member Webson's aunt, the unhappily married Elizabeth. While Browdy one-nights with a topless dancer, a doomed romance flares up between Elizabeth and Rettig. Tension builds, and explodes with a spectacular skydiving show.
