 Norbit (Murphy) is a normal person, who after being adopted by Mr. Wong (Murphy), ends up being married to the very large, Rasputia (Murphy). Norbit s childhood love, Kate Thomas (Newton) arrives back in town to buy the orphanage. Norbit sees this as his chance to get back together with Kate, until he discovers that she is in fact engaged to Deion Hughes (Gooding, Jr.). Norbit isn t going to lay this to rest, whilst he tries to survive life with Rasputia, and it looks like Deion also has something he would like to keep secret.
