A play based on a famous English case of a man being executed wrongfully on circumstantial evidence. Harry Baker and Alice Charlton meet at the preparations for a barn dance. He takes her home in his auto and this is the beginning of their love affair. At the dance each girl brings a necktie to match her apron. The boys choose their partners by drawing ties, which are wrapped. Clarence Morton, a rival to Harry, marks the wrapper of Alice's tie and gets her for a partner. Harry learns of this later and he and Clarence fight it out outside. A biting frost comes on and the dancers leave to protect the orange trees with smudge pots. Clarence comes across some smudge pots belonging to Jeff Robey, a neighbor of Harry, and starts to take them to his own grove. Robey comes along and accuses Clarence of theft. They quarrel and Clarence is accidentally killed by a pruning knife. Robey flees. Harry finds Clarence there; drops his own pruning knife and runs for help. He is arrested and tried for murder. Robey is drafted as the twelfth juror. Harry is convicted. At the crying of Alice, Robey breaks down and confesses.
