House believes a father is not having a smallpox like his daughter and breaks inside the quarantined room to prove his theory right.
"House M.D." would deal with a deadly disease next week and House is risking his own life. After a 200-year-old medicine jar found on an off-shore shipwreck shatters in a teenage girl's palm, she is admitted to Princeton Plainsboro for symptoms closely linked to smallpox.
When the Center for Disease Control's Dr. Dave Broda institutes a lockdown on the hospital and suspends House's team's ability to diagnose, Masters grows suspicious of Broda's motives and becomes convinced that the patient is suffering from a different disease. The girl's father soon experiences similar symptoms, and House is forced to make a precarious decision that puts his own life in jeopardy.
Meanwhile, Wilson and Sam comfort a 6-year-old chemotherapy patient who prompts them to examine their relationship.
"A Pox on Our House" airs November 15 on FOX. Cynthia Watros is back as Sam, while Dylan Baker and Devon Woods guest star as Broda and the chemo patient respectively.
