The city of Zootopia, where any animal can be whatever they want, has returned to normal after the case that united Officer Judy Hopps and the crafty Nick Wilde. But peace never lasts long in such a diverse city. New mysteries are emerging from the depths of Zootopia’s underground, and our heroes will be drawn into a case that will challenge everything they thought they knew.

In downtown Zootopia, Officer Judy Hopps was on her daily patrol with her partner, Nick Wilde. After solving the case of the wild predators, the city was quieter than ever… or so it seemed.

Judy:¨Nick, do you hear that? There’s something on the police scanner. It seems to be coming from the old underground district.¨

Nick:¨The underground district? I thought that place had been closed for years. Who would be doing something down there?¨

Judy:¨I don’t know, but we need to check it out.¨

The underground district, a complex of tunnels and abandoned train stations, is a place that most animals in Zootopia would prefer to forget. But Judy and Nick venture into its depths, following the trace of a strange signal.

Nick: What a cozy place. I’m definitely going to need a shower after this.

Judy: Nick, look at that… it looks like an improvised lab. What do you think they’re doing here?

Nick: This isn’t amateur stuff, Carrots. This looks like… advanced technology. But for what?

Judy: We need to report this to Bogo. This is bigger than we thought.

Back at the precinct, Chief Bogo listens to Judy and Nick’s report with a grave expression. It’s not the first time something strange has happened in Zootopia, but this seems more organized, more dangerous.

Bogo: If what you’re saying is true, we’re dealing with something serious. I want you to stay close to this. We can’t let the city panic.

Judy: We won’t let that happen, sir.

Nick: As if anyone would be scared by a couple of cops in an old tunnel, right?

Bogo: Do your job, and keep me informed.

As they investigate, Judy and Nick discover that Zootopia’s underground tunnels aren’t as abandoned as they thought. Several criminal gangs have been using the underground as a meeting point and for smuggling prohibited technology.

Judy: Nick, come look at this! They’re smuggling military technology. But… why? What are they planning?

Nick: This is worse than we thought. If someone wants to use this, they could cause a disaster in the city.

Judy: We’re not going to let that happen. We’ll stop them, no matter what it takes.
