Josh Hartnett casts himself into the sexual wilderness in this comedy about celibacy that is less crude than most teen-orientated offerings, and is even rather cute. Hartnett plays the recently dumped Matt, whose large number of one-night stands have left him depressed and doubting the existence of his soul. To rectify his shallowness, he swears off sex for Lent - the full 40 days and 40 nights - but the very next day meets the woman of his dreams. His only remaining option is to woo her the old-fashioned way, while his co-workers do their best to put temptation in his path. Although Matt's repeated exposure to inviting situations is an excuse to work through the gamut of male fantasies, these scenes are handled with humour and charm, while Hartnett proves to be an appealing comic lead.

Matt Sullivan's last big relationship ended in disaster and ever since his heart's been aching and his commitment's been lacking. Then came Lent, that time of year when everybody gives something up. That's when Matt decides to go where no man's gone before and make a vow: No sex. Whatsoever. For 40 straight days. At first he has everything under control. That is until the woman of his dreams, Erica, walks into his life.
