Alfred Hitchcock directed this disappointing misfire, memorable solely for the fact is that it is the final film from Hitchcock's early British period before he left for the Hollywood studio system and David O. Selznick. In the England of the 1800s, a group of ruthless smugglers, led by Sir Humphrey Pengallon (Charles Laughton), prey on ships by blacking out warning signals. When the ships crash on the rocks, the nefarious group loots the remains and kills the sailors. The plot kicks in when the beautiful orphan Mary Yelland (Maureen O'Hara) goes to visit her uncle Joss Merlyn (Leslie Banks) at a creepy hotel called the Jamaica Inn, the home of the gang of smugglers. Mary doesn't realize that Uncle Joss is one of them. Meanwhile, Lloyd's of London sends one of their ablest men, Jem Trahearne (Robert Newton), to investigate the recurring shipwrecks. Jem checks in to the Jamaica Inn, and when the coven of smugglers finds out who he is, they capture him and attempt to kill him. But Mary comes to his rescue and saves him. Through the inn, the smugglers try to recapture Jem -- along with Mary. Thrown together by dire circumstances, the two fall in love. Meanwhile, all the shenanigans occurring at the Jamaica Inn appear to be driving Pengallon insane.
