Penis envy... the almighty appendage. A small thing to wish for, but could it truly be the source of a powerful, more fulfilling life? Stacy and Lydia, two beautiful career girls, are about to find out. Stopping off at a trashy motel bar on their way back to L.A., they began a bizarre adventure after a chance encounter with... the penis fairy! He grants their wish for a trial "membership". Thinking this is the answer to all their problems, they begin an Odyssey of discovery about the benefits and "shortcomings" of the other half. It's a world filled uncontrollable urges, strange desires... a world where genders collide, drag queens preside, and body hair takes on a whole new meaning. Envy is an adult gender bending fairy tale that explores and explodes the myths of being male.
