The Undeclared War

9pm, Channel 4

If the recent publicity stunt for this thriller gave you a scare – a fake emergency news broadcast about an imminent cyber-attack, inspired by Orson Welles’s radio adaptation of The War of the Worlds – strap in for an intense series. Set in a disturbingly plausible vision of 2024, this six-parter follows the GCHQ analysts working secretly to block cyber-attacks. When an intern, Saara (Hannah Khalique-Brown), is the only person to spot a threat, alarm bells ring. Created by the Bafta winner Peter Kosminsky (who says it will “give audiences an insight into a world certain to impact our lives significantly in the years ahead”) and starring Simon Pegg and Adrian Lester, it is a nervy watch that is uncomfortably close to the bone.

The Lazarus Project

9pm, Sky Max

This mass-extinction thriller from Joe Barton, the creator of Giri/Haji, is watchable without being quite as singular as its predecessor. Tonight, George (Paapa Essiedu) is starting to wonder about his colleagues at Lazarus. Could this questioning of allegiances become permanent? Certainly, a few newly discovered facts make him uncomfortable about his former comrades. Phil Harrison

Sarah Beeny’s Little House, Big Plans

8pm, Channel 4

In tonight’s satisfying makeover, a young couple, Chrissy and Nick, who blew their cash purchasing a three-bed doer-upper in Poole, Dorset, desperately need Beeny’s budget tips. At the other end of the scale, Graham and Stephen started work on their house in Finsbury Park, north London, 24 years ago, blurring the lines between inside and outside with glass ceilings, foliage and a winter garden.

A deeply distressing case of child abuse lies at the heart of this story, about a five-year-old discarded by the people who should have cared for him most. With access to South Wales police, the documentary-makers uncover the shocking depths of the murderers’ deceit and explore the steadfast investigation that brought them to justice. Ellen E Jones

11pm, Sky Max

When the brood realise that their teacher Sam is making plans to escape with his wife, Zoë, they don their creepiest stares to try to stop them. Meanwhile, Dr Susannah Zellaby (Keeley Hawes) is adamant that she can save the children. HR

Paranormal Activity (Oren Peli, 2007), 9pm, Horror Channel
Here is the Casablanca of mid-00s found footage. Although much of its reputation has been stripped away by its punishing onslaught of sequels, the original Paranormal Activity is a classic. Deliberately spare (for the sake of budget), the movie follows a couple as they move around their house trying to figure out the cause of flickering lights and off-screen thuds. The seamlessness with which the mystery grows is astonishing – and the payoff brutal. Stuart Heritage
