Hanging upside down on a paralyzed roller coaster…

Gabe and Alex Zanadu aren’t having a fun summer experience riding the Crashin’ Coaster at a San Antonio, Texas theme park. A mysterious man wearing a black hoodie releases the safety bars of the stalled coaster cars. Passengers scream in terror and one boy falls three stories to the ground. The saboteur races to a maintenance exit.

Repeated disasters drag Gabe, Alex, their dogs, Thunder and Lightning, and friends into a cross-state chase for the criminals. The villain frames Alex. The FBI gets involved. Can the boys solve the case to clear their names and capture the man in the hood?
