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).

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.

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.

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.
