Catalog log
Broadcast listing — not a TV Flash recap.
A seemingly ordinary day with the usual collection of patients turns anything but when two prisoners intent on escape come to the ER for treatment. Aided by a conspirator posing as a patient, their desperate actions place a doctor in harm's way and force a nurse to become a tool in their plan. Soon, gunshots ring out, another doctor hits the floor, and a staff member's life is in jeopardy.

The first thing ER does, on September 19, 1994, is refuse to stand still. 24 Hours is not a premiere that introduces characters so much as a thesis about attention: overlapping cases, a camera that behaves like a person who cannot leave, and a county hospital that will still be there when the guest star is a movie. Michael Crichton put a novelist’s procedural brain under Warner Bros. television lights; NBC put it on Thursday. The gossip is Clooney. The text is velocity. If you only remember the exit economics,…
