In Lost Horizon, you will take control of Fenton, a small-time smuggler who was dishonorably discharged from His Majesty's Army. When Fenton finds out that his life-long friend, who is still a part of the British military, has gone missing in an expedition in the Tibetan mountains, he goes off to find out exactly what happened. What Fenton doesn't realize is that there is a lot more here than meets the eye.
Not only did Richard, Fenton's friend, disappear, he did so with the help of an old monk that showed him a secret passageway in the small village's mountainside. Apparently, the monks there are charged with keeping a massive secret, and the intrigued NAZI party, who has been showing up a lot around that area lately, are looking for this passageway. Now it's Fenton's job to track down his friend and find out what the strange secret he learned was before he disappeared.
