The nuptials of a Boston mayoral hopeful provide the backdrop for a string of farcically romantic scenarios, from the stuffy caterer (Jeremy Irons) bonding with his sweet if sight-impaired fix-up (Diane Keaton), the novice wedding planner (Maggie Grace) trying to live down her dumping-turned-viral embarrassment, and a duck boat guide (Andrew Bachelor) hunting across town for the passenger he's fixated with. Diego Boneta, Jessie McCartney, Melinda Hill, Andy Goldenberg also star.
