Watch Good Grief (1998) Official Trailer

"Good Grief" is a loose version of the "Peanuts" gang (notice the names) as high school kids who are into role play games. A group of seniors who have been into a fantasy role playing game named Monsters & Mayhem has begun to expand into normal teen activities, but Chuck wants the gang to stick with the games. Chuck has the idea to use their spring break to go off on a real treasure hunt for a golden statue that was buried for a publishers publicity stunt and never found.
