Callie Spengler (Carrie Coon) and her children, Phoebe (Mckenna Grace) and Trevor (Finn Wolfhard) family return, along with Gary Grooberson (Paul Rudd) to where it all started — the iconic New York City firehouse — to team up with the original Ghostbusters (Dan Aykroyd, Bill Murray, Ernie Hudson and Annie Potts), who've developed a top-secret research lab to take busting ghosts to the next level.

But when the discovery of an ancient artifact unleashes an evil force, the Ghostbusters new and old must join forces to protect their home and save the world from a second Ice Age.
