Successful New York City event planner, Catriona Masterton, has been on a mission to keep her new fiancé from meeting her family. This Thanksgiving, she's flat out of luck when orderly and regimented Ethan Crenshaw declares he will meet the Masterton Clan.
It's not that Cat's ashamed of her eccentric family, but how does one explain a mother with a kitchen gadget fetish, a father whose best friends are taxidermied field mice, and a super stoner man-child brother who lives in the basement? That doesn't even include the fiercely-proud Scottish grandmother with a proclivity for profanity.
Just when the visit couldn't get much worse, Cat is thrown a large curve ball when her ex-boyfriend and his family show up for Thanksgiving dinner. She's torn between the order and predictability Ethan and her life in New York City represent, while her family and the Midwest pull her in a different direction. Will Cat make it out of her hometown in one piece or is she willing to embrace the chaos? Mishaps, mayhem, and confusion ensue in this laugh-out-loud tale of familial pandemonium.
