Mary and Fred have married and become king and queen. Following the establishment of the Riverdale, they have created a prosperous new nation from the surrounding kingdoms, and banished the villains to the Rivervale, an island slum surrounded by a barrier where magic is suspended. Now, twenty years later, their son, Archie, who will soon be crowned king, announces that his first proclamation is to give four selected children from the Isle of the Lost a chance to live in Riverdale, away from the influence of their villainous parent, despite his father's protests. He chooses Kevin, son of Gladys; Jughead, son of FP; Veronica, daughter of Hermione; and Betty, daughter of Alice. On the island, Alice instructs the quartet to steal the Reggie's magic wand to release the barrier so she can take over Riverdale.
