Six friends are transported into the Dungeons & Dragons realm and must try to find a way home with the help of their guide 'Dungeon Master'.
Eric and Bobby retrieve a box for Dungeon Master. Dispite the fact that they were under strict orders not to open it, Eric gets curious. Just as he pulls the pin from the lock, Dungeon Master appears and warns Eric to place the pin back in place before it's too late. But Eric is taken by surprise when a force blows the top of the box off and releases He Whose Name Cannot Be Spoken. He is Venger's master, pure evil, and a powerful entity. The Realm is covered in darkness and a whirlwind envelopes the land. Dungeon Master then instructs the kids to flee on foot, and he joins them. When Eric demands to know why he should follow any further, Dungeon Master simply informs him: We are running, Cavalier, for our very lives.
Venger's got a new idea for eliminating his annoying young enemies, and pulls both a futuristic plane and a WWII Nazi fighter pilot into the Realm using his Crystal of Chronos. Venger intends to send Josef Mueller, the pilot, back to Earth to win the war for Germany, but after meeting the kids, Josef has other plans.
A lonely but smart orphan, Lorne, finds a lost amulet that leads him into big trouble. He and Eric become fast friends through the usual exchange of insults and bad-mouthing, and the gang teams up with him on their search for the Stone of Astra. But the wizard Korlok also seeks the Stone, and is close on their tail.
After getting yelled at by Eric for botching up a thieving job, Sheila is anxious to prove her worth by befriending Karena, a young woman who is more than she appears to be. Soon the gang finds themselves caught in the middle of a very bitter family feud when they realize Karena is related to none other than...Venger!
Tasmira, queen of the Faerie Dragons, is held prisoner by the greedy King Varen, an evil warlord who desires their treasure. Aided by the sassy little dragon Amber, the gang must free her and help her people find a new home.
The Darkling, a skeletal creature of darkness, kidnaps Hank. The kids have to convince the kindly Martha to help rescue their leader, before the Darkling claims his final victim and his Winds of Darkness destroy all light in the Realm. But Martha has been hurt by the creature one too many times and wants nothing to do with their quest.
