An ailing Army veteran charged with treason for leaking classified information refuses treatment unless he and his brother are given information about their late father, a war veteran. Meanwhile, Adams suspects that House is sick, so she recruits Wilson and the other team members to plan an intervention and investigate the illness.
House connects with a cloistered nun he’s treating who’s on the verge of taking her final vows. But when her condition worsens and requires risky surgery, it’s Chase’s judgment that’s compromised. Meanwhile, House and Taub try to out-prank each other.
A well-respected man (Jamie Bamber) collapses mysteriously, and while treating him the team discovers that he has been hiding secrets. His admission of them compromises his chances for recovery. Meanwhile, Chase and Taub rejoin the team, and Taub juggles his work life with raising two infant girls with two different mothers.
