In the spring of 1943 in Tunisia, a naked guy was running along a narrow mountain road. A tank was chasing him. The guy managed to hit the tank commander and driver mechanic with two stones, the tank lost control and fell down. All this was seen by the captain of the American troops who picked up the guy. The guy didn’t remember anything - neither his name, nor where he was from, he didn’t know the languages of those places, he had no idea where he was and what was happening. He began to quickly master the English language, they found his name and past, but his memory did not return. This haunted him all his life. Many years passed, he settled in a small town in Costa Rica. One day a strange visitor came to him, declaring that he was a man, but not an earthling, that they had known each other for about 6.5 thousand years, and invited him to follow him. Along the way, they had to change their appearance in order to throw off the scent of the American intelligence services, who were hunting for them. Will they be able to get to a place where the guy will be able to remember his past and regain lost knowledge.
