Coat check girl Bessie MacGregor is struck by the car of wealthy society woman Mrs. Templeton Orrin, who takes Bessie into her home while she recovers. Mrs. Orrin's brother, J. Warburton Ashe, says he loves Bessie and flirts with her, but when she learns he isn't serious about her, she flees the home, heartbroken. Bessie rents a room in a boarding house with her last dollar, then tries to find a job. Unable to find work, Bessie collapses from hunger one day in the boarding house in which she is staying. The landlady, Mrs. Flaherty and another boarder, a cheap hood named Tony Pantelli start to nurse Bessie back to health. Tony is in love with Bessie but hides his affections because he feels she is too good for him. A doctor diagnoses Bessie with a heart problem and tells her to remain in bed as much as possible. Ashe, realizing he was wrong in his treatment of Bessie, has no idea where she has gone so he heads off on a trip to England to try to forget about her. During a hunting expedition, he finds a mysterious chalice in the ruins of a monastery that the locals believe to be the
Holy Grail. Mrs. Orrin urges her brother to return home to find Bessie, and he brings the Holy Grail back to New York with him. Seeing Bessie needs medical care, Tony Pantelli tries to raise money by stealing the chalice and selling it to a pawnshop. The police later recover the chalice in a raid on the pawnbroker's shop. News of the cup's mysterious healing powers, and the way it glows in the dark, reaches the newspapers. The police return it to Ashe, who keeps it in his home on a mantle shelf. From her sick bed, Bessie reads about Ashe finding the Holy Grail in a newspaper. After Bessie tells Tony the legend of the Holy Grail, he steals the chalice, this time planning to use its magical powers to cure Bessie's heart failure. She touches the glowing cup and makes an instant recovery, but Tony is caught with the goods and put on trial for the theft. During the trial, Bessie and Ashe are reunited, and when Ashe has a religious conversion upon seeing the cup glow in the courtroom, he refuses to press charges against Tony who is released from custody. Tony leaves the courthouse heartbroken, after watching Bessie and Ashe embracing. Tony saved Bessie's life and reunited the two lovers, but at the end of the film, he walks out of the courthouse all alone. Later, the pawnbroker, now in
Sing Sing prison, confesses that the mysterious glow was from some radium he had placed in the chalice. ==Cast==
