When Humphrey Rump, a shy and overweight loner who rarely dates, finally brings a person of the opposite sex home to meet his raucous African-American family, everyone's on edge to see who this mystery girl could be. As it turns out, she's a beautiful, thin white woman and the surprises keep on coming. Jennifer Alden, Beau Billingslea, Georgette Brotherson, John Gipson and Willie Glover co-star in Stan Lerner's film adaptation of his own play.
