小胖子安格斯出身自一个古怪的家庭,父母都是同性恋者。男性化的母亲以卡车司机为业,独力抚养儿子。同住的外公思想开通,经常鼓励安格斯。过胖的身材一直使安格斯成为同学们的笑柄,虽然他在课业上和橄榄球队都表现出色,仍不免有点自卑。直至安格斯被他的死敌设计,指定他在舞会上跟他暗恋的啦啦队队长玛丽莎作舞伴,小胖子才在几番波折之下解开了心结。Angus is a large, pathetic 14 year old whose thoughts are most often filled with the image of one Melissa Lefevre. Angus is shy and thinks that he has no chance of ever 'getting' her. Being especially uncool, he is incredibly surprised (along with the rest of the school) that he is chosen to dance with her at the Winter Ball. The only one not surprised is the cool-kid who set him up to fail, but Angus' best friend is going to help him win the heart of Melissa by developing a new look for him.
