One Child
9pm, BBC2
Debut of an ambitious miniseries by Guy Hibbert, best known for writing the TV films Five Minutes of Heaven and Omagh. Mei (Katie Leung) is a young Chinese-born woman who has been raised by adoptive parents in Britain. The first she hears from her birth family in Guangzhou is a request to come “home” to help the brother she has never met, who is facing execution for a crime he didn’t commit. It’s both an effective thriller, and a wider parable of the mutual bewilderment that often characterises relations between east and west. Andrew Mueller
The Great Sport Relief Bake Off
8pm, BBC1
Ed Byrne presents the third of four floury skirmishes between another batch of nervy celebs. Ex-Ginger Spice Geri Horner, 90s poppet Louise Redknapp, war correspondent John Simpson and footballer-turned-pundit Jermaine Jenas all enter the tent like kids waiting to see the headteacher. They begin with freeform savoury tarts made without tins, and soggy the bottoms at their peril. The showstopper is particularly dastardly, requiring 3D biscuit depictions of famous sporting events. Julia Raeside
Midsomer Murders
8pm, ITV
The soul of middle England is a dark place. How else to explain the enduring popularity of Midsomer and its grotesquely imaginative slayings? On which subject, the horse-assisted murder of a local squire’s son, which begins tonight’s proceedings, is at the very least unnecessarily complicated. No matter: Barnaby and Nelson still put on their best serious faces as they investigate a case involving family secrets. In the meantime, light relief is offered by Sykes the dog’s refusal to go into kennels so the Barnabys can go on holiday. Jonathan Wright
Violent Child, Desperate Parents
9pm, Channel 5
While the likes of Supernanny have long propagated a mix of reverse psychology and general sternness to combat bad behaviour, counsellor Mandy Saligari takes things a step further by providing therapy for troubled kids on screen. This week, she steps in to help a single mum who is struggling with her eight-year-old son’s behaviour. As voyeuristic as it sounds, but also the perfect vehicle for the sorts of major transformations that reality docs are ultimately made for. Hannah J Davies
The 100
9pm, E4
The Hunger Games-esque drama returns for a third run, with the action picking up three months on from the conclusion to season two. Bellamy leads a search party to find the rest of the Ark, but trouble ensues when they’re confronted by members of the enemy Ice Nation. A twisty slice of dystopia, with just the right amount of teen-targeting fodder in the form of umpteen fight scenes and a cameo from Canadian pop star Shawn Mendes. HJD
10,000 BC: Two Tribes – the Final
11pm, Channel 5
As the tribes reach the final part of their challenge, wilderness motivator Klint Janulis is impressed that they’ve got the hang of hunting and foraging. Now he challenges them to “do something epic” that will become their legacy. There’s also the chance to reflect on what their experience in 10,000 BC has taught them about life, with a tearful Dan realising he shouldn’t have dumped his long-term girlfriend and George letting out his emotions. Then they’re off to a hotel to check their Facebook accounts. Hannah Verdier
Limitless
9pm, Sky1
This double bill of the crime drama based on the 2011 film of the same name shows signs of plateauing into routine, credence-busting superhero shtick by the second episode. That said, the opener gives it the best possible start, establishing protagonist Brian Finch (Jake McDorman) as an engaging guy to root for. An underachiever, he discovers he is immune to the side effects of a drug that hugely expands his mental capacities. His first job, however, is to evade FBI agents on a false murder rap. David Stubbs
FILM CHOICE
Total Recall
(Paul Verhoeven, 1990) 10pm, ITV4
This first spectacular, mega-budget adaptation of Philip K Dick’s mind-bending tale is altogether smarter and more fun than the plodding 2012 remake. Arnold Schwarzenegger is at the top of his game as an ostensibly ordinary (though very large) labourer who comes to recall that he was once a secret agent and powerful corporate forces have been messing with his mind. Cue dizzying paranoid delusions and state-of-the-art violence. Paul Howlett
