From Mondo Digital:
Run, Virgin, Run is about a small town with a surprisngly robust fertility rate. The menfolk attribute their prodigious offspring to a mystical wind that blows through once a year and sends them out into the wilderness, but in actuality their absence paves the way for local stud Michael (Jasinski) to plow his way through the willing women around him. For some reason the ladies don’t seem too concerned about the incestuous consequences of this arrangement, but hey, it’s a sex comedy. Michael finds himself in a seemingly endless series of erotic complications, including the memorable “naked in a barrel” sequence that found itself on most of the film’s ad art; eventually his romantic interest in the mayor’s virginal daughter threatens to put a stop to the baby boom, with everything sorting itself out for the romantic finale.
