Dark City, Texas. A terrible bandit named Jim Parasite runs an illegal whiskey distillery. Parasite wants to become the biggest and has therefore developed a magical powder that can shrink anyone. The local Texas Rangers, led by the brave Ranger Tom, try to stop Parasijt, but are lured into a trap. Tom and his Rangers are shrunk and put into whiskey bottles. In an escape attempt, the bottle containing Ranger Tom ends up in a crate that is shipped to Belgium and thus ends up in the hands of Lambik, who is given a crate of whiskey by Theofiel Boomerang. Suske, Wiske, Aunt Sidonia, Lambik, Jerom, and Professor Barabas hear the story and decide to help Ranger Tom. Barabas will try to enlarge Ranger Tom again, and the rest travel to Dark City to stop Jim Parasijt.
