Tonight's TV highlights

Unreported World 7.30pm, Channel 4 Journalist Ramita Navai uncovers the plight of refugees fleeing the regime of African nation Eritrea, and a life of conscription or imprisonment, for a safer existence in Israel. In leaving, their lives become even more perilous as they contend with armed guards and unscrupulous smugglers who see them as a product to be secretly spirited across borders. Navai meets desperate people who have given up everything to risk the journey, one that – even if they overcome the considerable risks – still has no guarantee of anything even approaching a happy ending. Phelim O'Neill Foo Fighters: Back and Forth 11.50pm, BBC2 Dave Grohl and band celebrate 16 years of the tough alt-rock that's landed them Grammys, platinum discs, stadium concerts and small fortunes. The film looks at the making of Wasting Light, which was recorded on old equipment in Grohl's garage, and charts the band's career, from the first demos that Grohl made in the dying days of Nirvana. The band may not have burned as brightly as some of their peers, but have survived to be one of the biggest rock acts around. Martin Skegg Modern Family 8.30pm, Sky1 The extended Pritchett clan find ways to celebrate Jay's birthday as the second season comes to a close tonight. All he wants is a quiet fishing weekend – so no chance he's going to be catching much of either. Phil runs into an old college frenemy while out shopping with Gloria at the mall ("Dude! Is that your wife?" "It would appear so . . ."), the kids get busy editing a birthday video, and Claire and Mitchell get stuck in their childhood home. One of the most consistent half-hours of funny around at the moment. Richard Vine Annie Nightingale: Bird on the Wireless 9pm, BBC4 Once upon a time, the radio threw up a generation of bona fide broadcasting icons, DJs obsessed with new music and in tune with their listeners year after year. Now it barfs out Fearne Cotton. But the fact that Annie Nightingale is still on the radio, 40 years since her first show on Radio 1, proves that someone, somewhere, is still doing something right. Thankfully, this film is less a hagiographic tribute to Nightingale's tenacity, more a journey through the counter-culture with a woman who packs as many decent anecdotes as she does high-profile fans. Nosheen Iqbal Great British Menu 6pm, BBC2 The last lamb's been roasted, the final potato has been mashed. Now, after 10 weeks of cook-offs, it's time for the final episode and the huge "people's banquet", a street party for 100 guests of honour, somewhat strangely hosted by Barbara Windsor. But before all that, they have to choose a winner. Watch the finalists, helped by judges Prue Leith, Matthew Fort and Oliver Peyton, make their last-minute preparations, and then take your pasta off the boil because, sorry, there's no turbot for you tonight. Caroline Corcoran In Treatment 10.15pm, Sky Atlantic Another double-bill of therapy and revelation as both Mia (Hope Davis) and April (Alison Pill) show up to Paul's office for early-morning sessions. April's exhausted, having pulled an all-nighter while trying to finish a project for her architecture course; Mia's fuming when Paul arrives a few minutes late from his weekend back home. In Treatment is one of those rare TV shows that affords its characters a tangible past: when Mia drops some hints about Laura's deposition, it's a chance for us to see just how much Paul is still affected by their relationship.
