10 Years ago:A group of university friends are studying abroad in Australia, having the time of their lives. Sun-kissed skin, whirlwind romances, all-night parties - they think it will never end, that nothing bad could ever happen to them. When the exclusive Outback Experience begins, they can't wait to travel the country, swim with sharks, hike in the national park and see the outback. But then one of the group turns up dead and their trip of a lifetime becomes a nightmare. Now:New evidence has been found and the group have returned to Australia to be interviewed by the police. One of them knows what happened all those years ago, but they will do anything to keep the truth buried.
