Finally, at the very beginning of this week’s programme, paramedics Iain Dean (Michael Stevenson), Teddy Gowan (Milo Clarke) and Indie are having a lovely start to their shift, complete with a comedy roadtrip-esque singalong, when they’re suddenly stopped in their tracks by a horror movie-like twist, in what is a great opening scene in an engrossing episode.
Casualty instalment Internal Affairs – Episode 4 airs on BBC1 on Saturday 05 April 2025 at 9.10pm. The episode is available on BBC iPlayer from 6am.
