In the previous episode, the crew of the Nautilus encounters a swarm of giant cuttlefish, one of which entangles the ship’s screw, preventing it from moving. Captain Nemo leads the crew in a fierce battle against the creatures, using axes and harpoons. Despite their efforts, one of the crew is killed, leaving Captain Nemo grief-stricken, and the Nautilus remains adrift for days before resuming its course through the Gulf Stream.

We pick up at the start of chapter 20.
