Protection
Sunday, 9pm, ITV1
Happy Valley fans will get a buzz out of seeing Siobhan Finneran in her first kick-ass lead role in this nail-biting crime drama. She plays flawed but formidable detective Liz Nyles, whose job is to make sure no harm comes to people under witness protection. So what happens when a family she’s in charge of are shot dead? “Is there any chance you’ve slipped up here?” her boss asks, quite rightly. But when Liz discovers that a young girl has survived the shootings, and that a colleague she’s having an affair with was at the scene of the crime when it happened, the plot thickens with corruption, moral grey areas and propulsive twists. Katherine Kelly also stars. Hollie Richardson
Towards Zero
9pm, BBC One
The final part of Agatha Christie’s whodunnit, which slightly suffers from the loss of Anjelica Huston’s inimitable presence, now that her Lady Tressilian has snuffed it. But who killed her? With another victim found, Matthew Rhys’s troubled detective Leach relies on “strange” clues to get answers for the big “point zero” reveal. Anjana Vasan, Jack Farthing and Oliver Jackson-Cohen also star. HR

Ten Pound Poms

The relocated period drama continues, as the Roberts family adjust to life in Oz circa 1957. “Australia brings out the best in you!” crows a travel brochure, yet nurse Kate (Michelle Keegan) is potentially facing deportation, and there’s tragedy in store for the Skinners. Ali Catterall
Forensics: The Real CSI
9pm, BBC Two
The final case in this sometimes hard to bear crime investigation series is about an elderly man whose body is found after what looks like a brutal attack in this home. It’s up to the West Midlands police to confirm when and how he died, and track down the killer. HR
Tempting Fortune
9pm, Channel 4
A £300,000 prize pot is at stake, and all these 12 contestants need to do is make it through a gruelling, 18-day trek in the Malaysian jungle, while host Paddy McGuinness tempts them astray. Accepting any little luxury – such as a pool swim or a taxi boat – will mean decreasing prize money and increasing group tensions. Ellen E Jones

Skincare, 10pm, Sky Cinema Premiere
Hope (Elizabeth Banks) is a perma-smiling beautician to the stars in LA, and is about to launch a new product line when a competitor opens up across the street. Soon, she is getting anonymous calls, her tyres are slashed and her email account is hacked. Assuming the rival is to blame she fights back, aided by “life coach” friend Jordan (Lewis Pullman). But appearances can be deceptive. A mix of woman-in-peril thriller and beauty industry satire, its success rests on Banks’s finely contoured performance, alternately fierce and fragile. Simon Wardell
