Lost Treasure

The movie takes place in the present day, when a policeman obtains one half of a treasure map, and gives it to his brother to figure out. The policeman is then captured by a mobster who was looking for the treasure, who then forces him to come to the island to help him find it. Meanwhile, his brother hires a small plane (with a female pilot and two incidental passengers) to take him to the island, but a storm ends up stranding everyone. The two groups are forced to survive in the jungle while also clashing with each other.
