Kathy is married to Peter. Now she can't help but wonder how things could have been if she got together with her old boyfriend, Tom. Being married prevents from doing that so she asks her friend, Emily to go to him and see if she can sleep with him then tell Kathy how it was. When Emily tells Kathy that things were awesome, their friendship suffers, at the same so does Kathy's marriage. Things get even more complicated when Emily learns she's pregnant, and she's not certain if it's Tom's or her boyfriend, Elliot. 　　译文(2): 凯西嫁给了彼得。现在她忍不住想，如果她和她的前男友汤姆在一起，事情会变成什么样子。结了婚就不能这样做了，所以她让她的朋友艾米丽去找他，看看她能不能和他上床，然后告诉凯西这是怎么回事。当艾米丽告诉凯西一切都很棒的时候，他们的友谊受到了损害，凯西的婚姻也一样。当艾米丽知道自己怀孕了事情就更复杂了她不确定是汤姆的还是她男朋友艾略特的。
