Weil ärztliche Behandlungsfehler nicht gut analysiert werden, passieren viele immer wieder. So auch im Fall von Dieter Kleinschnieder. Er wäre fast an einer Vergiftung gestorben.

Thirteen has been in prison for the past year, but the real mystery for House is what she did to get there. When she exits the prison, she is taken aback to find him waiting for her, and unaware he’s got plans for the two of them for the next few days. As House probes Thirteen for more information about her crime, intent on solving the puzzle of her mysterious incarceration, they travel to an annual spud-gun competition and join forces to compete against House’s much younger, overconfident rival, and along the journey uncover secrets and truths about each other. At the hospital, the team treats a science teacher suffering from severe respiratory illness, and when the team inspects the patient’s house for clues to his illness, they immediately learn he’s a hoarder. But upon a second visit to obtain more information, they uncover something in the many piles that shocks them. Also, Taub tries to get back into the dating scene, but winds up retreating to his old habits.
A patient is admitted after breaking out in a severe rash triggered by caustic chemical exposure at his blue-collar job. As the team treats him, they discover that he has led his wife to believe that he is still maintaining his once-lucrative real estate career. Meanwhile, Cuddy is honored with an award and needs House to be at the charity event for support, but his attendance is threatened when his patient's battle to survive forces him to question his practice and his own happiness. Also, Chase and Masters teach each other a lesson in forging meaningful personal and professional relationships.
