Of all the numerous reality game shows that enveloped British TV in the wake of Big Brother, Lost was one of the least publicised, low key, and most entertaining. The premise was ultra-simple. Three pairs of contestants were abandoned, blindfolded, somewhere in the world armed only with a meagre amount of possessions and a limited ration of local currency. They'd no idea where they'd been taken, and were deliberately deposited in as desolate, inhospitable and lonely environment as possible. They then had to get back to London as quickly as possible, and the first team home won a bottle of champagne - plus the chance to do it all again next week.
