After more than two decades together, Andrew Lane and Miles Kettering-Lane are going through a nasty divorce. Not only are they unraveling their relationship but also their business—Miles once had a popular home show on cable with Andrew serving as his producer/manager—the failure of which they blame on each other. Now, they’d be happy to never, ever see each other again. But the daughter they both adore, Kelly, announces she’s getting married, and that means one very important thing: a wedding. Thrown together, at event after event—meeting the in-laws, planning the wedding, throwing an elaborate engagement party—the two clash over everything until, their future in-laws, Bradley and Pudge Lincoln and Terry and Lissa Collins, try to take over the entire wedding. The Lincoln-Collinses' are very wealthy, to quote Pudge, “People think we’re in the one percent but that’s so embarrassing. We’re barely in the two percent!” Andrew and Miles realize they have to work together in order to compete with the overbearing Lincoln-Collinses' and give their daughter the wedding she deserves. Along the way, they realize things just might not be over between them.
