A tale of competition at its most cut-throat, this feisty contemporary drama surveys the raw ambition of Laura Pickler (Jennifer Garner), the wife of Bob Pickler (Ty Burrell), Iowa's long-reigning champion butter carver. For 15 years, Laura has relished her high-profile role as the beautiful, loyal helpmate to her affable, artistically gifted husband.
However, when Bob is pressured to retire and allow someone else a chance at glory, an indignant Laura decides to enter the competition herself. She is first in line on sign-up day, only to see her odds of victory fall below 100% with the arrival of an unlikely yet formidable contender: 10-year-old Destiny (Yara Shahidi), the African-American foster child of local couple Julie and Ethan (Alicia Silverstone and Rob Corddry).
And that's not all. Bob's would-be mistress, bad-girl stripper Brooke (Olivia Wilde) also declares her candidacy, as does his #1 fan, Carol-Ann (Kristen Schaal). Facing three opponents, mocked by her step-daughter Kaitlen (Ashley Greene) and furious with her husband, Laura resolves to do whatever it takes to win. And if that means resorting to sabotage - and recruiting her dim-witted former boyfriend Boyd (Hugh Jackman) as a co-conspirator - then so be it.
