Knock On Wood

S1, E19: A series of messages sent by a damsel in distress are floating wooden bottles offering a reward to anyone who will rescue her. Vic identifies the wood from the bottles as Bird Cherry so the crew set out for Bird Cherry Island. But when they get there the damsel tied to the only tree on the island looks familiar, and as Halvar tries to turn the Drakkar around, there is Sven’s ship, blocking their path!
