Input (English): In the 1970s on the Binlusai islands, a young mother is killed when she was running with her son from an evil presence in an abandoned Roman Catholic leper colony. In the present day, a group of four young men and women are travelling to the island to take part in a survival game run by TV channel Search Planet headed by Chen Jiadong (Philip Keung). Also on the boat is the television presenter Stanley (Jessica Xu) and cameraman Ken (Shaun Tam). The eight people have been split into four pairs where they are given a map which leads to a flag; their aim is to survive without any supplies, and the winning duo gets a grand prize of one-million dollars. As they approach the island, their ship is attacked by something unknown under the water and most of their luggage is lost. Shen Yilin (Yang Mi) has preserved her map which she gives to her partner Peng Fei (Jordan Chan). The group is immediately attacked by wild boars. One of the boars is killed by Japanese competitor Ono Hiroshi (Hayama Hiro) with his hunting knife. That night they stumble across the remains of the leper colony, where a message written in Chinese on a stained-glass window in the chapel states that they will be killed. Funeral urns appear with each of their names written on them.Later that night, Guan Zhichun (Janel Tsai) and Tina (Maggie Lee) try to get Peng Fei to hand over the map while Yilin tries to persuade him to return it to her. Peng Fei is then attacked by an unknown force and disappears. Meanwhile, Chen Liangliang (Anya Wu) has found a notebook hidden in the building. Zhang Xiaolong (Wong You-nam) has an idea to figure out what is happening but everyone suddenly passes out. The next morning, Shi Nan (Tsui Yin-yau) is found to have blood on his shoes but denies that he is the killer. After Liangliang goes missing with the notebook, chaos breaks out among the group.
