Play for Today: Never Too Late
9pm, Channel 5
“Of all the retirement villages, she walks into mine.” In the first of this drama anthology inspired by the classic BBC strand, Anita Dobson plays quick-witted septuagenarian Cynthia, who realises charismatic old flame Frank (Nigel Havers) is her new nextdoor neighbour.

Celebrity Race Across the World
8pm, BBC One
Anita and her father Bal are the first to leave checkpoint one, as they head to El Zonte in El Salvador – a leg of the journey dangerous enough to warrant a “no travelling after dark” warning from the producers. They, and the teams behind them, can go via the Guatemalan jungles, the Belize beaches or the less-visited Honduras. HR

The Ridge
9pm, BBC Two
Scot-in-New Zealand Mia (Lauren Lyle) continues to ignore every convention of the crime-mystery genre as this unusual drama continues.

Lyle’s unpredictable energy makes her character, and the show, compelling. Jack Seale

If you’ve ever wondered what Sanjeev Bhaskar would look like dressed as Jack Sparrow (no?), then look no further, as the mildly sadistic comedy gameshow concludes. Plus, Reece Shearsmith makes a questionable cuppa with help from Maisie Adam, and Alex Horne gets a good hose-down. Hannah J Davies
