Nicole broke up with Matt months ago and is now engaged to someone else. He's very good-looking and has no trouble finding other lovers, but that doesn't help because he's still obsessed with wanting her back. Then he gets the inspiration that swearing off sex for Lent (all forms of sexual activity, even kissing or masturbation) will give him the perspective he needs. So of course a few days later he meets a woman and they fall in love. Now Matt sees his vow as a personal matter, and won't even tell her about it, but his friends think otherwise, and now the complications begin... 我知道你在她们身下的感觉。禁欲四十天。我也赌10块他至少还能干上一天一夜。作为喜剧片的导演，他一直在巧妙的苦苦暗示我们。吞进青春，吐出沉默和无奈。胖子看电影 NO.55《禁欲40天》。有时候就要。跟自己过不去。小色情拍出了小清新。只记得哈奈特了。让我想到了我的手淫和遗精的电影。 对于甜蜜的恋爱，马特（乔什·哈奈特 Josh Hartnett 饰）也曾有过梦幻的憧憬，而屡屡遭遇的失败爱情却让他对女人这种难缠又奇怪的生物彻底的死了心。在又一次残酷被甩之后，悲痛欲绝的马特做出了一个对于所有男人来说都无比沉重的决定——禁欲40天。在这不近女色的40天中，马特希望自己能潜心修炼，最终成为一个无欲则刚的优秀青年。 而就在禁欲的生活让马特觉得神清气爽的时候，那个名叫艾瑞卡（莎妮·索萨蒙 Shannyn Sossamon 饰）的美丽女孩来到了他的身边。虽然被艾瑞卡迷得神魂颠倒，但马特并没有忘记自己最初的誓言，更何况自己的周围有一群损友都在等着看自己的笑话。扳着手指头，马特觉得时间似乎走得越来越慢。
