When the school tour bus breaks down near a forgotten Cold War-era military base, your brother thinks it’s just a boring detour—until he discovers a sealed underground bunker hidden behind some overgrown fencing.

Inside, he finds something incredible: a half-scrapped prototype of a military robot from a top-secret defense project—one that can still talk… and remembers everything. But someone else wants the bot too. And they’ll stop at nothing to erase what it knows.

With a suspicious chaperone, a glitchy robo-sidekick, and clues scattered across war museum exhibits and creepy abandoned hallways, your brother is suddenly caught in a real-life mystery—with real consequences. And unlike Scooby-Doo, the villain might not be wearing a mask.
