Danger Mouse and Penfold are in a training simulation when one of DM's flying kicks damages the holodeck with catastrophic consequences. They wake to find they've been in a three year dream, that they aren't secret agents and work in IT instead, and the Danger Agency has been a figment of their imaginations! Whilst Penfold and Squawk quickly settle into a life of menial office work, DM struggles to accept life as Dane G Mouse.
