Zobel and Karl are a long time gay couple who live together in a trailer home with Lizzie, Zobel’s spunky daughter from a heterosexual misadventure. Together these three form a team of thieves who eke out an existence as pickpockets. After a botched job, Karl becomes unable to work, forcing Zobel and Lizzie to seek out a new partner. Lizzie recruits Rudolf, the boyishly charming town misfit. Reluctantly, Zobel allows Rudolf to join them but warns him to never break the golden rule: “No exchanging of bodily fluids within the team.” This dictum becomes increasingly difficult to live by as Lizzie’s cravings and Zobel’s own passions toward Rudolf intensify. Eventually, the golden rule is broken by Lizzie…and then again by Zobel (unbeknownst to Lizzie, of course). An intricate love triangle soon develops amongst the three that is shaped by deception, desire, and betrayal.

The Trio is a comedy spinning with freewheeling sexuality. Its cast of characters includes Zobel, an aging queen; his tired lover, Karl; and Zobel's feisty daughter Lizzi. All three travel around in a mobile home living off their earnings from their pickpocketing business. When Karl becomes unable to work, the ambitious young Rudolf, a boyishly charming misfit, takes his place in their cozy band of thieves. Although Zobel decrees "no exchange of bodily fluids within the team," both father and daughter get the hots for their newest member, and a very interesting ménage à trois ensues.
