King Irv, monarch of the Wholesale Kingdom is surprised one day when a troop of Vikings shows up on the doorstep of Warehouse Castle. It seems that the Norsemen had stumbled onto the wreckage of Hershel the Merlin's old time machine on some future beach and, fooling with the contraption, suddenly found themselves thrown back through time to the court of King Irv. Demonstrating to the Vikings how the contraption works, King Irv and Hershel, find themselves in the new world, the Viking's Vinland, in the twelfth century. To further complicate matters, one of the young Viking sailors trips, falls and puts the tip of his sword into Hershel's time machine, rendering it useless to bring them back home to the Wholesale Kingdom. The time machine does work, off and on, taking them to modern day San Francisco and then back to the old west of America, everywhere except back home, until a major hurricane changes everything.
