Ying-Juan, a 30-year-old chef, is constantly belittled about her weight by her mother. She attends a weight-loss centre only to placate her mother`s demands that she loses weight. She befriends Wu, a happy-go-lucky delivery man who struggled with his weight in the past and then with Xiao-Yu, a young student who secretly enjoys wearing women`s clothing. The more Ying-Juan commits to her new diet regime, the more she becomes less of herself.
