Given the question: I am a movie director and I just received the following movie plot. Could you help me answer this question? If not, let me know by writing "Not answerable". Plot title: Jamaica Inn Movie plot: Jamaica Inn is the headquarters of a gang of wreckers led by the innkeeper Joss Merlyn (Leslie Banks). The wreckers are responsible for a series of engineered shipwrecks in which they extinguish coastal warning beacons to cause ships to run aground on the rocky Cornish coast. Then they kill the surviving sailors and steal the cargo from the wrecks.

In another part of the inn, the gang convenes to discuss why they get so little money for their efforts. They suspect Jem Traherne (Robert Newton), a gang member who has been with them for only two months, of embezzling goods. They hang him from one of the rafters of the inn, but Mary cuts the rope afterwards and saves his life. Together, Traherne and Mary flee from the gang. They are almost...
