相伴到永远

Kathy is married to Peter. Now she can&#39t 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&#39s marriage. Things get even more complicated when Emily learns she&#39s pregnant, and she&#39s not certain if it&#39s Tom&#39s or her boyfriend, Elliot.
