In Harvey, Louisiana, 1978, a derrick man named Monkey works the oil patch and lives at Clay and Minnie’s, a boarding house / bar run by ex-con and charming mobster Clay Boudreaux. One day a teenage boy named Sean arrives, just kicked out of his home in Minnesota. Monkey takes Sean under his wing, shielding him from Clay’s criminal operations, and from Janny, Clay’s 16-year-old niece. Discovering what everyone already knew about Clay and Janny, Sean convinces Monkey to get Janny out of Harvey. Forty years later in 2018 Sean is back to find out whatever happened to his old friend. What he discovers alters everything he understood about his life, as Monkey’s mysterious death threatens to converge with his own.
