Harold (PAUL WINFIELD) and Dolores Williams (MARY ALICE) are a middle-aged, African-American couple who, twenty-some years ago, adopted two orphaned Vietnamese kids. Despite their tumultuous early years, Mai (LAUREN TOM) and Dwayne (CHI MUOI LO) are now generally well-adjusted young adults, with Mai being married to Vinh (TZI MA) and Dwayne hoping to propose to his nurse girlfriend, Nina (SANAA LATHAN).
The happily family scene is disrupted, however, when Mai announces that she's located their biological mother, Thanh (KIEU CHINH), and is bringing her over to the States. While Mai is happy to have her real mother back in her life, Dolores is hurt by the woman's presence as is Dwayne who must put up with this stranger living with him and his roommate, Michael (TYLER CHRISTOPHER), who's dating Samantha (WING CHEN), a male transvestite.
With Thanh's presence putting a strain on the many relationships within the Williams clan, Dwayne must figure out his true cultural identity, whether he can accept his biological mother into his life, and how all of that affects his engagement to Nina.
