Snake 4: The Lost World

The story

A storm causes a plane to crash on a remote Pacific island, leaving behind a few survivors. Among them are Hao Ran, a failed businessman who wants to die so his family can collect on his life insurance policy, Ruan Ning, his ex-lover who also happened to be on the plane, and Li Jun, whom some of the passengers recognize but can't remember from where. Their only hope of survival is to find a walkie-talkie so they can call for help. It's in the cockpit, which has become separated from the rest of the plane on the way down, but that means a long and dangerous journey across the island, and dealing with a bunch of other giant creatures and each other.
