In 1979 New York City, married-with-child Marvin falls for another man. He leaves his wife Trina to set up home with his new lover, and attempts to form a stable family unit for his son Jason. This plan doesn't go so well, with Mavin trying to slot his boyfriend Whizzer into Trina's former role of homemaker and Jason suffering anxiety about having two dads. Things then get even more complicated when Marvin's psychiatrist Mendel, who has been charged with shoring up this delicate situation, falls for Trina.
