Mysterious Island(2011)

Mysterious Island is a 2010 horror-survival film that opens with a deadly incident at an abandoned leper colony in the 1970s, then jumps to the present day. A TV network organizes a survival game on a remote island, recruiting four pairs of contestants who must navigate without supplies to find a hidden flag for a million-dollar prize. The group includes presenter Stanley and cameraman Ken, along with contestants like Shen Yilin and her partner Peng Fei. As their boat approaches the island, an unknown force attacks from beneath the water, destroying most of their equipment. Stranded and separated, the survivors must contend with the island's dark history and the mysterious presence that killed a young mother decades earlier. What begins as a game becomes a desperate fight for survival against forces beyond their understanding.
