Albus Dumbledore, a powerful and wise wizard, knows the dark wizard Gellert Grindelwald is planning to seize control of the wizarding world. Unable to move against Grindelwald directly due to a blood pact from their past, Dumbledore enlists the help of Newt Scamander, an endearingly awkward magizoologist with a talent for understanding magical creatures. Newt, along with his team of trusted friends and unpredictable brother, is tasked with a mission that will test their wits and bravery. They must thwart Grindelwald's expanding influence and his growing legion of followers, while unforeseen threats and new beasts complicate their quest.

As Grindelwald's power intensifies, the stakes are raised for the team's covert operation. Grindelwald's agenda to elevate pure-blood wizards over all non-magical beings generates global instability, and he cleverly manipulates public fear to erode resistance. New alliances are formed, and loyalties are tested, as Dumbledore's ragtag team infiltrates the enemy's ranks, uncovering Grindelwald's broader scheme to win not only magical supremacy but also the hearts and minds of the wizarding community worldwide. The team's deepening connections and the secrets they uncover about themselves and each other shape their mission in profound ways.
