Deep Labyrinth

One summer afternoon, Shawn goes for a drive with his quarreling parents
and his beloved dog, Ace...but the trip quickly turns sour when the
family car suffers a flat tire in front of a seemingly abandoned
mansion. Ace is clearly upset by something inside the mansion, and leaps
out of the car to investigate. Shawn's parents follow Ace, but don't
return. As Shawn tentatively approaches the dilapidated structure, the
entrance door swings open, and he's drawn into a magical vortex. Now,
with Ace at his side, Shawn must embark on the greatest adventure of his
life...into the heart of the Deep Labyrinth.
