Virginia Sullivan, called Red, carries the family nickname that goes to the first daughter of each generation, and she arrives at the Sullivan house with her fiancé Nathan Kessler to introduce him to her grandmother and her brothers Marcus and Jake. A man staggers up the driveway badly hurt, speaks the name Gabriel, and is gone before Nathan brings Virginia back. Marcus, the sheriff, takes charge of the scene.
