Dungeons & Dragons is an action-adventure series based on the role-playing game of the same name by Wizards of the Coast. The show ran three seasons from 1983 through 1985. In the story, a charming thief sets out on an epic mission to find a lost artifact with a group of odd adventurers, but things quickly go awry when they cross paths with the wrong kind of people.
