Overview: A group of drunken mods arrive at the hospital in a shocking state, and Ken Hopkirk soon makes the grim discovery that they have been drinking industrial alcohol supplied by their friend, theatre technician Alun Morris. Meanwhile, a fourth member of the boozing group is brought in and has his stomach pumped immediately - but it soon emerges that the illicit hooch has blinded him. Elsewhere, Mr Rose and his surgical team treat a widow with a gangrenous toe at her farmhouse, and student nurse Samantha Beaumont receives a telling-off for laying out operating instruments in an incorrect order.
