In Ghostbusters 6 (2025), the world has regained its relative calm since the icy chaos of Frozen Empire. The veteran team has receded into advisory roles while the new generation of Ghostbusters—led by Phoebe Spengler (Mckenna Grace) and her partner Lucky Domingo (Celeste O’Connor)—runs the front-line operation in New York City. But peace seldom lasts. A mysterious surge in ghost activity around the Times Square underground tunnels signals a threat even older than the one they faced before.

The opening scenes take us deep beneath the city where ancient spirit-rifts have begun to tear reality. Phoebe and Lucky investigate a series of bizarre disappearances tied to subway stations. They discover that the tunnels are a conduit for an primordial entity that once predated humanity’s ghosts—a being of pure energy that uses the modern city’s infrastructure as a network. As the entity awakens, ghosts around the world become hyper-active and violent.

Meanwhile, the original Ghostbusters—Ray Stantz, Peter Venkman, and Winston Zeddemore—reconvene in a cameo-rich sequence, offering their insight and proton-pack tech upgrades to the new team. Their presence reminds us of legacy and change: the mantle has shifted, but the mission endures.

The central emotional arc involves Phoebe’s fear of failure and of becoming irrelevant in a legacy-driven world, while the entity’s threat forces her to trust her team rather than rely on inherited wisdom. Lucky’s comic-relief competence balances Phoebe’s self-doubt, and a subplot involving a ghost-friend reawakens themes of friendship and memory from earlier films.

In the climactic sequence, the Ghostbusters plunge into the subterranean network, battling spectral storms and navigating collapsing tunnels. The final showdown takes place in a cavern beneath the city where the entity is manifesting through the subway rails. By combining old-school proton pack tech, newly invented ghost-net traps, and Phoebe’s experimental ghost-link device, they manage to sever the conduit and calm the world’s ghostly surge.

Ghostbusters 6 delivers a fresh take: blending the humour, heart and gadget-glamour of the franchise with a new scale of threat and a deeper look at legacy and leadership. It honours the past while clearly pointing to the future—inviting both longtime fans and new audiences to rally behind the proton-packs once more.
