The script focuses on world-renowned cutting-edge architect Davenport Lear (Dern). Nearing retirement, he summons his four dysfunctional children Glenn (Hall); Regan (Michalka); Kent (Bishop) and Rory (James Hoare) and their spouses, respectively Tyler (Stephen Ellis); Tom Cornwall (Astin); Delia (Ivy Matheson); and Natalie (Amy Argyle).

When they hear the bombshell that he has decided to marry his personal assistant that Sunday, it sets off an explosive round of devious behavior and conflict as each of them jockeys for position, borne by self-interest, greed and jealousy.
