Isaac "Ike" Hendrix is a young law student who is married to Christella and works as a taxi-cab driver in New Orleans.

While out on a night of fun with Christella and their friends, he participates in a hypnosis act and becomes an unwilling host for the restless spirit of J.D.

Walker - a hustler who ran numbers during World War II and managed a black-market meat plant.

Ike finds himself gradually being taken over by the sociopathic J.D., even eventually going so far as to adopt his hair and fashion style, mannerisms, and psychotic tendencies, often hurting Christella in the process.

Once fully possessed by Walker, Ike commits havoc all over town before making his way to the church where Theotis' younger brother and Betty Jo's widower, Elija, former gangster, now working as a preacher.

Having left the gangster life behind to pursue faith full time, Elija relays this to his brother and says that this is God's way of justice; he decides to join Theotis to hopefully free Ike from J.D.

At the meat plant, Theotis was enraged by Betty Jo's derisive chiding of him and her threats to expose Roberta's true paternity, so he impulsively slashed her throat before hiding.

Elija accidentally discharges the weapon and kills Theotis, prompting him to run away as Roberta mourns over his body and the police arrive.

He decides to go to the precinct and lies that Theotis accidentally shot himself, while defending Ike's actions as an act of possession by J.D., who is gone.
