Young Mini (Sammi Cheng) descends into depression when her relationship with handsome pianist Kurokawa (Rikiya Kurokawa) comes to an end. To cope, she eats so much that she gains 200 pounds, literally becoming unrecognizable to her former boyfriend. While bemoaning her weight, Mini meets the heavyset Fatso (Andy Lau), who assists her in losing the excess pounds so that she can reunite with Kurokawa. But in the process of getting back to her original size, Mini slowly begins to fall for Fatso.
