When Two Won't Do (2002)

It takes viewers on an intimate road trip across North America - from a polyamory conference in the Catskills, a swingers' convention in Las Vegas, to long-term multipartner families in California. Along the way, the filmmakers try to learn from these relationship veterans, while navigating their own fledgling polyamorous relationships. The results are as giddy, painful, sad and loving as real life tends to be.
