Her Strange Experience (1917)

Marie is kidnapped and held for ransom. John, one of the crooks, rescues her at great risk to himself. Later, when she is safely returned to her parents and her fiancé, Roy, they see a man hurt in the park. It proves to be John. Marie recognizes him and takes him home. He becomes a servant in the family. They are giving a reception. John is serving the guests. He finds a note pushed into his hand as he stands before the curtained window. It says that unless he hands over a gem, which is displayed among the wedding presents, the crooks will get him. He tries to steal the jewel, but Marie prevents it. She then causes the arrest of the crooks who are waiting to receive the jewel.
