Chong-kwai welcomes his friends Ted, May, Kofei and April from Hong Kong to his home in Thailand. He shows them a book which describes a game of ten ways to see ghosts.
After Kofei goes missing halfway during the game after he relieved himself on a tree in the woods, April stays behind in Thailand to try to find him, while Ted and May return to Hong Kong. April disappears too later.
