As usual, his mates start bagging on Ander's plan for Ders-day before he even unveils his plan, but this really looks too nerdy: the Viking expedition, celebrating his Nordic roots, at the city museum, while they just dream of a childish fast-food chili diner. Desperate to 'redeem' his coolness deficit, Ders buys a replica of the showpiece historical helmet, pretending he's stealing the real one. However Adam and Black can't resist out-staging him by real exhibit theft. So they must run dealing with technical security, curator Saul Kingston, his museum staff and precursors of the following dinosaur exhibition, including deliverers and a pair of raptor mascot actors.
