To the amusement of their adult children and friends, long-divorced couple Don and Ellie Griffin are forced to play the happy couple for the sake of their adopted son's wedding after his ultra conservative Catholic biological mother unexpectedly decides to fly halfway across the world to attend. With all of the wedding guests looking on, the Griffins are hilariously forced to confront their past, present and future - and hopefully avoid killing each other in the process.
