The script focuses on world-renowned cutting-edge architect Davenport Lear. Nearing retirement, he summons his four dysfunctional children Glenn, twins Regan and Rory, Kent, and Regan's husband Tom Cornwall to a weekend family retreat in one of his signature architectural creations. When they hear the bombshell that he has decided to marry his personal assistant Diana that Sunday, it sets off an explosive and humorous round of devious behavior and conflict as each of them jockeys for position, borne by self-interest, greed and jealousy. Rounding out the cast is Davenport's driver and valet Tyler, Diana's daughter Delia, and Kent's hot date Natalie.
