Widower Michael Bluth has been working for his father's development company since he was a teenager manning the family's frozen banana stand, and he and his son George Michael have gone so far as to move into one of the company's model homes. So when his father George Sr. throws his retirement party on the family yacht, Michael expects that he will be announced as his father's successor. Instead, Michael gets two surprises: His mother is the new President, and his father is under investigation by the SEC. So Michael has to hold his wildly dysfunctional family together.
Michael suspects that George Sr. is running the business from inside prison. George Michael is made manager of the banana stand, and Michael gives GOB a letter to mail after Lucille suggests that he be included in the business.
Lucille suggests that Buster be included in the family activities, but Buster is reluctant to leave his mother's apartment in hopes of avoiding Lucille 2. Meanwhile, Tobias takes over the directing duties for the high school play to rather disastrous results.
Determined to not be upstaged by his actress girlfriend, GOB decides to pull an elaborate escape at the Orange County Prison, where George Sr. is being held. Meanwhile, Michael falls for GOB's girlfriend Marta.
To help the company's image, Lindsay returns to her roots - charity fund raisers. While Lindsay is the most charitable member of the family, Michael tries to prove he's a more charitable person by helping a woman he thinks is his mother's housekeeper. Maebe, defying her parents, decide to break into the permit office, using George-Michael's help, and they learn a shocking secret about the Bluth Company. Meanwhile, Buster accidentally bids on his mother's social rival Lucille Austero at a charity bachelorette auction.
Michael gets a tip about the company's international accounts, and has GOB question the office secretary Kitty about them. But that's not before Michael does the unthinkable - setting up a conjugal visit between George Sr. and Lucille.
It's time for the annual Living Classics Pageant, and Barry makes a deal with Michael to get George Sr. out in time to take part in the pageant's signature exhibit - Michaelangelo's The Creation Of Adam. But there is no god when George Sr. makes plans to escape.
Michael cannot remember anything about the car accident he and Lucille were in. While he's trying to piece together the accident, GOB thinks Michael is planning to escape to South America with his father. Meanwhile, Lindsay makes repeated visits to the prison in hopes of scoring a date.
