Will Freeman的生活无忧无虑，就像个永远长不大的孩子。在创作了一首热门歌曲之后，他再也不用为生活烦恼——他现在有的是钱，有的是自由时间，身边有的是美女佳人。别人说他是个终日只会吃喝玩乐的单身汉，但他一点也不反感——他喜欢这样。当贫穷的单身母亲Fiona带着古怪精灵的11岁儿子Marcus搬到Will的隔壁时，你可以想象Will有多么惊讶——他们破坏了他的完美世界！Marcus经常不打招呼就跑到Will家中「做客」，Will很不高兴。他不好撵他走，但是又不想跟一个小屁孩做朋友……直到他发现单身父亲对女人来说有着不可抗拒的诱惑力！这个发现改变了一切！Will迅速和Marcus达成一项「协议」：Marcus假装自己是Will的儿子，作为「回报」，Will允许Marcus待在自己家里玩乒乓球，吃美味的牛排——奉行素食主义的老妈绝不会给他吃这种东西！逐渐的，这个大男孩和这个小男孩之间产生了「忘年友情」。Will越来越喜欢Marcus到自己家中来玩，他甚至主动承担起照顾Marcus的责任。事实上这段忘年交让他学会了以前不可想象的事情：关注自己，关心他人。
