Chaos brings the Higgins family closer together as Godcat and Devilcat face their final challenge: making humans go against their own nature.

It's good vs. evil as the cats compete in the God Games for control of Heaven and Hell. Travis' friends turn against him. Marv inherits a mess at work.

Devilcat takes Godcat as her plus-one to a wedding in Hell. Travis goes back in time to undo his biggest regret — but changing the past has consequences.

Devilcat takes Abbie and the kids on a hellish road trip to Halcyon Springs to meet her long-lost mother. Godcat helps Marv ask for a promotion.

Devilcat and Godcat go to SeaWorld, Marv drags Abbie to a "work thing" aboard a corporate blimp, and Greta helps Travis track down a troll.

Greta enters a rocket-building competition sponsored by billionaire Jefflon Bezmusk. Meanwhile, Travis moves out — and the cats get inside Marv's head.

Greta goes to work with Marv, and Godcat and Devilcat watch the movie "Armageddon." Travis and Abbie follow Aidan to Heck — not Hell.

To show Travis they really love him, Abbie and Marv plan a last minute half-birthday rager. Godcat summons the cherubs to see the wonders of Earth.

Sent to Earth in the body of a cat, God moves in with the dysfunctional Higgins family, then takes game night in a wildly different direction.
