George Sr. suggests a last-ditch effort to save the family by holding a fund raiser to raise money to pay their legal expenses. Michael suggests to Lindsay that she take over the house work, and he sends George-Michael to an expensive boarding school. Meanwhile, Maeby has trouble with a snowboarding film and Tobias tries to be a "discipline daddy".
As the family's upcoming deposition nears, they participate in a mock trial, hosted by Judge Reinhold. Michael searches for a mysterious witness on the list, while the prosecuting attorney makes Michael an offer he cant refuse. Meanwhile, GOB practices his ventriloquism act, and Buster fakes a coma to get out of testifying.
Michael's quest to locate the mysterious "N. Bluth" leads him to Nellie, a prostitute who he believes is his long-lost sister, and the woman who just might be able to clear everything up. Meanwhile, Buster's fake coma incurs the wrath of real doctors.
GOB heads to Iraq via his participation in the U.S.O., where he is quickly arrested and being held by the U.S. military. The prosecutors believe this is treasonous, so Michael and Buster head to Iraq to free GOB. There, they visit the house they built and discover what's really inside.
After returning home from Iraq, George Sr. is finally cleared of all charges, and Michael is relieved to be the head of a successful company for a change. The real brains behind the madness is revealed, and just as the family begins to celebrate their victory, a whole new set of problems emerge.
