Terrestrial Hollyoaks Channel 4, 6.30pm They just keep on coming back. The other week it was Mandy; this week it's Ruth, who obviously got fed up of 60-minute makeovers - and who can blame her? She returns for Jack's funeral, but we all know Jack's not really dead, don't we? Elsewhere, it's all getting even more ridiculous, with policeman Calvin procuring heroin for Sasha.

Highland Emergency Five, 7.30pm Five have produced a fantastic series charting the work of the Highland emergency services. Not only do they have to carry out life-saving rescue missions in which seconds count, they have to contend with the most inhospitable landscape and weather in Britain. In the opening instalment, an RAF search-and-rescue team is scrambled to an incident at the summit of Ben Nevis, the Cairngorms ski patrol deals with a bad break on the slopes, and the Stornoway coastguard is called out to a painful injury on the remote island of Scarp.

The Secret Millionaire Channel 4, 9pm The first series of this programme won acclaim and awards, so it's no surprise a seven-part second was commissioned. Tonight, entrepreneur James Benamor, who is worth more than £70m and spent his youth involved in drugs and petty crime, operates as a youth worker in Manchester's poor Moss Side district, where he becomes emotionally involved despite his reputation as a tough businessman.

Digital Britain's Missing Top Model BBC3, 9pm Tonight the spotlight falls on Kelly Knox, winner of Britain's Missing Top Model, as she steps up to the big stage with her prize: a photoshoot for fashion magazine Marie Claire with the world-renowned photographer Rankin. The show also looks back at some of the major highlights from the competition and hears from all eight girls - their perspectives on the whole experience, what it was like meeting each other for the first time, living together in the penthouse apartment, the friendships made, the bitching and back-stabbing, the photoshoots and the nerve-wracking eliminations.

True Stories: The Thin Blue Line More4, 10pm In 1988, the acclaimed documentary-maker Errol Morris reconstructed and investigated the case of Randall Dale Adams, a man who was kept on Death Row in Texas for 12 years when he was falsely convicted of killing a policeman. This film was the result. Morris examined the fantasy and reality that surrounded the main characters in the story, to prove that Adams was - as he had always claimed - entirely innocent. The evidence presented in the film effectively won Adams a pardon - but, in a curious epilogue, he later sued Morris to reclaim the rights to his life story and pursue further film offers.

Radio The Choice Radio 4, 9am and 9.30pm Michael Buerk returns with the series on individuals whose lives have been transformed by taking one particular decision.
