The answer is:
"Oh Lord, we pray Thee, not that wrecks should happen, but that if they do happen, Thou wilt guide them to the coast of Cornwall for the benefit of the poor inhabitants".So ran a prayer in the early XIX Century, before there were formal lighthouses, in Cornwall, a lawless corner of England . . .A ship is off the coast, making its way towards the shore on a stormy night. A man leaves Jamaica Inn on horseback and goes to the bluffs to conceal the warning light and cause the ship to run aground. A band of men wait on the shore for the inevitable shipwreck. As the frigate grinds itself to death on the rocks, the men kill all the surviving sailors and loot the cargo.It is daytime, and a stagecoach is on a road along the coast. The driver says to his companion that "Queer things" go on at Jamaica Inn. Inside the stage coach, a young Irish woman Mary Yellen (Maureen OHara) comments that she intends to stop at Jamaica Inn, whereupon those who hear her seem dumbfounded and horrified.Mary first tells, then yells at the coachman to drop her off there, but he rudely speeds past the place and stops near the mansion of Sir Humphrey, the local squire (Charles Laughton). She gets out to complain, but the coachman throws her trunk to the ground, tells her to ask Sir Humphrey for help, as he has a soft spot for young women, and drives off.Sir Humphrey is having dinner with upper class friends inside, grandly spouting off upper class platitudes. The butler tells him that a young woman has come and asked for him, so he leaves the dinner and goes to meet her. She reveals to him that she needs to go to Jamaica Inn to find her aunt Patience, wife of the innkeeper, and intends to move in with them, as her mother has recently died . Sir Humphrey is much struck by her beauty, offers his support and help anytime she needs anything, and orders a servant to prepare two horses so they can ride to the inn and carry her trunk.At first Mary mistakes the rude man who answers the door to be an underling, when it is actually her uncle Joss...
