Travelling along the Dnieper River in Eastern Europe to get a new sword, reputably invincible, for Halvar, who broke his own, the Vikings think they find the real deal around a statue of Angantyr, the king of the Goths. But when they come back to their drakkar, it drifts away downstream. To catch up with it, they borrow horses from local farmers. The situation aggravates when the drakkar drifts away to a waterfall. Vic must find a way to save the Vikings' drakkar.
