The Accidental Honeymoon (1918)

Young Kitty runs away from home to avoid marrying a man she doesn't love. Her car breaks down on a country road and she meets Robert, a young artist who has just been turned down by a woman he loved madly and is about to commit suicide by lying on the railroad tracks. He sees Kitty in trouble and decides to help her. They get the car running, but it runs out of gas in front of a farmhouse. The farmer, mistakenly believing that the two are married, has them share a bedroom for the night. The next morning Kitty's father shows up looking for her and discovers that she has "spent the night" with a stranger. Complications ensue.
