When a group of college band mates reunite 15 years after graduation to sing at a friend's wedding, they take a break from their less-than-perfect lives to spend a long weekend at a cozy Hamptons beach house with their spouses, children, friends and one Swedish nanny in tow. Reuniting with lifelong friends provides them with some much-needed perspective on how their lives have progressed - and in some cases, regressed - since their college heyday. WEDDING WEEKEND stars Molly Shannon ("Kath & Kim," "SNL"), Elizabeth Reaser (Twilight, "Grey's Anatomy") and Rosemarie DeWitt (Rachel Getting Married, "Mad Men").
