Kyle (Owen Wilson) and Peter Reynolds (Ed Helms) are fraternal twins who were raised by their mother, Helen (Glenn Close), as their father died before they were born. Kyle is dating his pregnant girlfriend Kaylani (Jessica Gomes) and is wealthy from royalties for his image on BBQ sauce labels. Peter is a divorced proctologist with a teenage son (Zachary Haven) who resents him. Shortly after Helen's wedding, Peter recognizes an actor on ''Law and Order: SVU'' from photos of his supposed father and confronts Helen.
