The House M.D. episode in which House is trapped under a collapsed building is titled “Help Me.”
“Help Me” is the season-six finale, broadcast on May 17, 2010. The story begins after a crane collapses at a construction site, leaving multiple people injured and trapping a woman named Hannah beneath the wreckage. House becomes personally involved in the rescue and medical decisions.
The episode is unusual because much of its central medical drama unfolds outside the hospital. House must work with emergency responders while confronting the limits of treatment, time, and physical access to a patient. The crisis also affects his relationship with Cuddy and his understanding of his own emotional state.
The title is sometimes confused with “Everybody Dies,” the series finale, or “After Hours,” another season-six episode. “Help Me” specifically belongs to the sixth season and ends with House seeking psychiatric treatment.
