Theresa Jones (Zoe Saldana) is in love with her boyfriend, Simon Green (Ashton Kutcher). She plans to introduce Simon to her parents when they renew their vows. To the surprise of Theresa's parents, dad Percy (Bernie Mac) and mom Marilyn (Judith Scott), Simon is white. Differences in race make Percy apprehensive to accept Simon, which creates tension between everyone, disrupting Percy and Marilyn's vow renewal and driving a wedge between Theresa and Simon. The film is loosely based on the 1967 film "Guess Who's Coming to Dinner," in which the roles were reversed and portrayed by Katharine Houghton and Sidney Poitier.
