Alicia Crosby is a hugely successful children's fashion designer based in Los Angeles. Her personal life is equally successful as Alicia suspects her boyfriend Will Randall is going to pop the question any day now. But first, Alicia must survive meeting Will's family, which means getting down and dirty in their family's annual 'Reunion Races' where she is up against everyone from Will's mom, Barb, his dad, Doug, his seemingly sweet Grandma Dorie, to even Will's ex-girlfriend, Kris.
