After a rough crossing of the North Sea, Spike the Viking is washed ashore. He ends up in Transilvania, which seems to be just an ordinary village. However, he finds out that his shipmates have been captured, and are being imprisoned in the dungeons of the local castle. Spike must rescue his friends from the mysterious castle, but first he has to escape from the (apparently friendly) villager's house where he finds himself, as the door won't open.
