Station 19
10pm, Sky Witness
The producers of the medical drama Grey’s Anatomy launched this companion series last year, following the lives, loves and high‑pressure hoses of the attractive squad manning a nearby fire station. Season two returns to the skyscraper blaze cliffhanger that left many of Station 19’s first-responders in mortal peril, forcing young Lt Herrera (Jaina Lee Ortiz) into some life-or-death decisions. The escalating crisis is cut with timely flashbacks to help clarify key relationships, adding yet more soap to all the water. Graeme Virtue
Behind Closed Doors: Through the Eyes of the Child
9pm, BBC Two
One in five children in the UK has witnessed or experienced domestic abuse. This documentary on the subject is, as you would expect, a tough watch, but if it spreads awareness then it will have done its job. You may find it hard to believe the levels of vindictiveness and cruelty on display. Mike Bradley
Cleaning Up

This serialised sequel to Wolfgang Petersen’s 1981 film opens in autumn 1942. The allies have broken the Enigma code and the tide is turning against Hitler’s deadly U-boats.

Pure
10pm, Channel 4
The usual millennial-in-the-city dramedy gets a necessary revamp via this mental health memoir. This week, sex-obsessed Marnie (Charly Clive) makes a new London friend (Joe Cole from Peaky Blinders), who not only helps guide her to a diagnosis but introduces her to felting. And no, that’s not a weird sex thing. Ellen E Jones
Hypothetical

Iceman (Felix Randau, 2017), 10pm, Sky Cinema Premiere
Writer-director Felix Randau imagines the story behind a 5,000-year-old death: that of a man whose remains were famously discovered in the ice of the Alps in 1991. It’s a familiar tale of an attack on a village and the revenge of the iceman (Jürgen Vogel), but, spoken in the ancient Rhaetian tongue, it’s oddly compelling. Paul Howlett
