About Clayton[]
When Sam, as Clayton, the sheriff of Baton Rouge Parish in fictional 1955 Potterville, Louisiana, who's a widower with a 10-year-old daughter, Abigail, finds his deputy, Deputy Sheriff Bart Aider, dead in a nearby swamp, Leta Aider, who is unstable, blames Abigail for his death, and that of her daughter Violet, who disappeared from their home in 1953, this after Abigail had been the last person to see their daughter Violet before she disappeared and presumably died two years before.
Sam, in his leap mission, is to save young Abigail from the raging wrath of Leta, who winds up cornering her in the Fuller house, demanding that she confess to the crimes of murder of her husband and daughter; in the original timeline of events, both Abigail died in a house fire after Leta set it ablaze with her in it on the night of August 8, 1955.
Sam, as Clayton, visits the mental hospital where wife Laura Fuller is hospitalized in hopes of trying to get more information about Leta, who had, two years earlier in a heated argument with her, insulted her and called her crazy, sing that she should be committed and "not allowed to have anymore crazy children". Al, with Ziggy's help, warns him that Leta is at the Fuller home, tormenting and threatening Abigail, trying to get a murder confession out of her, as she then sets the home ablaze, it's now the sheriff's, or Sam's, mission to save and rescue Abigail from the house by breaking a bedroom window and getting her to jump out of it, as he is able to do so, confronting Leta, who is able to sneak out of a backroom door as the fire blazes before he, or the Sheriff, dies in the blaze as a fiery wooden beam collapses and falls down from the ceiling, as Sam leaps.
