Life becomes even stranger when the figures on the new School Crossing sign come alive and talk to the children. Is this magic ... or are these really beings from the 4th Dimension?

Deep in the forest they stumble upon a dangerous drug-dealing criminal gang and a poacher's trap. Before they can escape, they are kidnapped and thrown into a scary basement while their kidnappers decide what to do with them. What fate awaits the children?

With the help of the Signpost Kids they must risk death to outwit the kidnappers and bring these ruthless criminals to justice before it's too late. Will they escape the Poacher's Trap? Or will the Boss make them disappear forever?
