Mason Young is the former Pastor of a congregation based on a community of boat-based church-goers. After a botched attempt to stop a robbery in St. Louis, a near fatal gun shooting left Mason with a new drive to help people. Feeling his survival was a miraculous sign from God, he established a church on the water of Lake Ozark. Dozens of motorboats met on the water each week as Mason, speaking over a loud speaker, practiced his faith passionately.
However, unbeknownst to him, Mason's hymnals were used to smuggle heroin by the Snell associate, Ash. This news was brought to him and instead of tolerating the illicit behavior under the roof of his church, he rebelled against the Snells and Byrdes, an act that cost him the life of his wife, Grace.
His infant son, Ezekiel (nickname Zeke), surviving the murder, was eventually sent to be a ward of the state. After Mason rashly kidnaps Wendy in exchange for Zeke, Marty arranged for Zeke to be returned. During the exchange, Marty and Wendy try to coerce Mason to surrender but he attempts to kill them. In the melee, Mason is shot and killed. Zeke is then taken in by the Byrdes until a suitable family could be found.
