Our Shirley Valentine Summer
9pm, ITV
New series in which eight single women – Melinda Messenger Siân Lloyd, Nancy Dell’Olio, Aggie MacKenzie, Ninia Benjamin, Lizzie Cundy, Annabel Giles and Ingrid Tarrant – depart for a Greek island in the hope that they can transform their lives. The conceit is quite simple: that they should follow in the footsteps of movie heroine Shirley Valentine as they go in search of love, friendship and happiness. Entertainingly, things turn out to be more complicated. MB
Prison
9pm, Channel 4
Remarkable two-part documentary set in HMP Durham, where drugs are a major factor in the lives of its inmates. We follow the illicit drugs trade run by Michael, who is suspected of concealing a mobile phone, and learn about the amazing capacity of human beings to insert things up their own backsides, a nine-inch blade included.

Why Size Matters
9pm, BBC4
The first of a two-part documentary in which Hannah Fry interrogates the science of size. She begins by picturing what life would be like were Earth much larger than it is, learning about Gigantopithecus, at 3.5 metres said to be the biggest ape ever to have existed, and imagining what a 15-metre-tall human body would look like.

Ramsay’s 24 Hours to Hell and Back
10pm, Channel 4
Having mastered the skill of restoring the fortunes of restaurants through the power of shouting alone, Gordon Ramsay has decided to up the ante. This new series sees him carry out the same task again, only with a self-imposed 24-hour time limit. He begins at a struggling Italian in New York State. GM
The Week That Wasn’t
10pm, Sky1
Last in the series of Alistair McGowan and Ronni Ancona’s topical comedy. “Satire” wouldn’t be the right word for the quickfire overdubs of the week’s news footage, since the gags rely on loose puns and casual stereotypes more than swingeing critique. This week, expect an excess of Harry Kane and Gareth Southgate. JS
Detroiters
11pm, Comedy Central
The second series of the eccentric Detroit-set comedy begins. Ad men Sam and Tim are on a roll. But will a commission from Michigan Science Center drag them too far out of their comfort zone? Smart, witty and displaying a genuine civic pride that’s refreshing and rare in portrayals of the Motor City. PH
Film choice
The Apartment 10pm, Sky Arts (Billy Wilder, 1960)
Jack Lemmon’s insurance clerk hardly deserves to get the girl: Shirley MacLaine’s sweet lift operator. He’s low enough to lend his apartment to managers conducting illicit affairs, rising higher in the corporation thanks to his little favours. Integrity is at a premium in one of Billy Wilder’s funniest, most cynical satires. PJH
