Entertainment Weekly has released the official plot to the Fantastic Beasts and Where to Find Them movie.
To read it, simply highlight the space in-between the two Snitches.
Eccentric magizoologist Newt Scamander (Oscar winner Eddie Redmayne) comes to New York (for a reason we won’t disclose) with his trusty weathered case. This case is one of those way-way-way-bigger-on-the-inside magical devices, and within are expansive habitats for a collection of rare and endangered magical creatures from Newt’s travels around globe. He discovers the American wizarding community is fearfully hiding from Muggles (who are called “No-Maj” in the States, more on that here) and the threat of public exposure is an even graver concern than in the UK (remember the Salem witch trials?). Fantastic Beasts is the story of what happens when this uniquely skilled English wizard travels to wiz-phobic America and a variety of his creatures, some quite dangerous … get out of their case.
