1955, Kenya. A group of four acquaintances set out to drive from Nairobi to London, via the Sahara desert, in a 8 horse-power Morris Traveller. Under the leadership of Alan Cooper, a down-on-his-luck farmer, the group was made up of a worldly field biologist who recorded the whole trip on her 8mm cine camera, a genteel schoolmistress of uncertain age in search of romance, and a 17-year-old boy whose mother had insisted that the trip would make a man of him. What united them was a desire for adventure.

As they set off through Equatorial Africa the omens seemed against them. The Mau Mau uprising against British rule in Kenya was at it's height and the days of colonial rule were ending. Their journey was to take them through an Africa that very soon would cease to exist. But it was the desert that turned their joyride into a nightmare. What began as an adventure ended as a desperate fight for life in the blazing sands of the Sahara. Trek brings this story to dramatic life and is a classic account of survival against the odds.
