Knocked Up (2007)

When Alison Scott is promoted in E. Television, she goes to a night-club to celebrate with her older married sister Debbie. Alison meets the pothead reckless Ben Stone and while having a small talk with Ben, Debbie's husband Pete calls her to tell that their daughter has chicken pox. Debbie leaves the place but Alison stays with Ben, drinking and dancing along all night; completely wasted, they end up having a one night stand. Ben does not use a condom and eight weeks later, Alison discovers that she is pregnant. She calls Ben and they decide to try to stay together and have the baby. However, Ben needs to grow up first to raise a family of his own.—Claudio Carvalho, Rio de Janeiro, Brazil
