In 1927, the Magical Congress of the United States of America (MACUSA) is transferring the powerful dark wizard Gellert Grindelwald from their maximum security prison to London to be tried for his crimes in Europe. Grindelwald escapes during the transfer, aided by his follower and MACUSA employee, Abernathy. Three months later in London, Newt Scamander appeals to the Ministry of Magic to restore his revoked international travel rights following his misadventure in New York City. While at the Ministry, Newt runs into Leta Lestrange, an old Hogwarts classmate who is engaged to his brother, Theseus, an Auror in the Department of Magical Law Enforcement. The Ministry offers to restore Newt's travel rights if he assists Theseus in locating the obscurity Credence Barebone, who has resurfaced in Paris. Credence may be Leta's long-lost brother, Corvus Lestrange, the last of a long line of pure-blood wizards. Grindelwald believes only Credence can kill his equal, Hogwarts Professor Albus Dumbledore. Newt, however, declines, refusing to choose sides, and the Auror Grimmson is dispatched instead..
