Danger Mouse's over-reliance on gadgets prompts Colonel K to send his top agent on a tech-free nature retreat. Unbeknownst to Danger Mouse, Greenback has the same plans for his daughter, Delilah, whose social media obsession has also spiralled out of control. Back at HQ Penfold is tasked with protecting the entire world from the threat of super-villainy. Stripped off his gadgets, DM struggles to adapt to life in the wilderness and, when a talking pine cone called Conni begins to offer him survival tips, he begins to question his own sanity. Soon enough, Delilah catches wind of DM's presence and she plots to destroy him as a means of getting back into her Dad's good books.

There's relief all around when Penfold's pilfering of Squawk's gadgets and clandestine late night trips to shady warehouses turns out to preparation for his taking part in `bot battles', a fight club for homemade robots. Penfold hopes to enter his own creation, Geoff, into the competition but is sidelined by an overeager Danger Mouse and his own robot, the CRN 3000! When the CRN 3000 obliterates all challengers, DM's call for a worthy opponent is answered by Megahurtz.
