Together since junior high, and the proud parents of a one-year-old, 19-year-olds Rebecca and Luis are getting married. But Luis must contend with his father’s constant warnings of an imminent divorce. And when Rebecca accidentally posts an open wedding invite on Facebook, total strangers start RSVP’ing. But things really start to go awry when Luis’ 15-year-old best man and brother, Fernando, gets engaged to Rebecca’s maid of honor, Angelina. After being accused of stealing the bride-to-be’s thunder, Angelina skips the bachelorette party. So Rebecca holds a game of rock-paper-scissors between the remaining bridesmaids to replace her.
