Tonight's TV highlights

Hostage In The Jungle 7pm, BBC2 Terrific documentary recalling the bizarre tale of Ingrid Betancourt . In 2002, Betancourt was running for the presidency of Colombia when she was kidnapped by the narco militia that trades as FARC. She was eventually held for a little over six years before a dashing rescue by Colombian commandos in 2008. This film allows Betancourt to tell her story, which is variously buttressed and disputed by some of her fellow hostages, including her now estranged campaign manager Clara Rojas, who had a child with one of her captors. An astonishing study of extremity. AM Wonderland 9pm, BBC2 Country Life magazine's "girls in pearls" are the focus of tonight's film. Five former high society brides, photographed for the posh tome at the time of their engagements, tell the stories of what happened afterwards. Arabella, Camilla and a Sackville-West sit in their capacious drawing rooms, talking of thwarted expectation and hellish upkeep on the family pile. But with the subtlety and skill you'd expect from Wonderland, this is more than just a flick through a dog-eared glossy rag. They always seem to find the interviewees you want to listen to. JNR Grand Designs 9pm, Channel 4 Never mind the downturn – Grand Designs is recession-proof, a property programme that's about more than the bottom line. This is a show that deals in passion and backstory as much as bricks and mortar and so far this season there have been some admirable, even some tearjerking moments – unfamiliar territory for Kevin McCloud and his permanently-raised eyebrow. Tonight's episode features Kathryn Tyler, who has plans for a Scandinavian-style eco house in Falmouth. JR Young Voters' Question Time 8pm, BBC3 Richard Bacon hosts a live debate on the day that Chancellor George Osborne unveils the government's Spending Review. Voters under the age of 25 will have the opportunity to quiz a panel of politicians and "famous faces", and air their views on what they think of the £83 billion worth of cuts. Billed by the government as a financial necessity and by the Labour opposition as more dangerous than Margaret Thatcher's gutting of public services nearly 30 years ago, the young 'uns aren't going to be short of points to debate. MS Mad Men 10pm, BBC4 Serial downloaders of Mad Men have been breathlessly banging on for weeks about how fantastic episode seven of this series is. The standards are obviously already sky high but this 45 minutes of TV is as good as anything you'll see this decade. Set against the backdrop of the Clay-Liston heavyweight rematch in May 1965, there's little here but Don and Peggy as they live out a dark night of the soul working on a Samsonite ad. Here Don is just about hanging on to himself as he avoids making a phonecall that he knows will break his heart. WD The Office: An American Workplace 10pm, Comedy Central What with 30 Rock, Community and the (not yet aired in the UK) Parks And Recreation, US channel NBC is on something of a comedy roll. The Office is something of a godfather to them all and still going strong, despite the announcement that star Steve Carell is to leave at the end of the seventh series currently airing in the US. The start of series five here begins with Michael Scott and the team taking part in a corporate weight-loss challenge aided by a pre-diet glutton fest including, mmm, a cheese fountain. Brilliant. WD
