Meanwhile, on the planet, crewman Hogan is devoured by a gigantic worm creature.[notes 1] The natives of the planet kidnap Kes and Neelix. Chakotay attempts to negotiate for their return, but this does not go well and he, Kes and Neelix plus other crewmen flee and are forced to hide in one of the caverns that the giant worms lives in. The natives attempt to smoke them out with a fire.
Back at camp, things are going wrong, although the crew have managed to find food and warmth. Ensign Wildman's baby falls ill and continues to get worse and Chakotay's team is still missing. Janeway gathers her own crew to go after Chakotay.
Inside the caverns, a mis-step leads to a crew member waking and getting eaten by the worm. Outside, Janeway has B'Elanna and two others draw off the natives with a distraction. It works, allowing them to put out the fire and get the rest of the crew out. The worm ends up buried under tons of rock dislodged by Tuvok and others as they escape.
Suder and the Doctor risk their lives to repel the Kazon. Suder, under orders from Tom Paris, who is with a Talaxian convoy, attacks the engineering section of Voyager. His goal is to sabotage the phaser weapon systems. He succeeds, but is shot in the back by a dying Kazon and perishes moments after. The Kazon attempt to destroy Tom Paris' shuttle but the sabotaged phaser ends up killing most of the Kazon and so they decide to abandon Voyager. Seska herself has been mortally wounded; she stumbles into Janeway's ready room and dies next to her child, who survived. Maj Cullah, one of the few survivors of the attack, momentarily grieves for Seska, and then takes the baby and leaves.
On the planet, volcanic eruptions have forced the Voyager crew and the natives to move out together. Chakotay gains the respect of the natives when he rescues one of their children from a lava flow. The leader of the tribe gathers together plants that help Wildman's baby to recover.
The crew and the natives both watch in bewilderment as Voyager descends to the planet to pick them up. Tom Paris greets Janeway and the crew on the bridge and explains of Suder's deeds. In Sickbay, there is a brief conversation over the bodies of Seska and Suder; Tuvok wishes for Suder the peace he had not been able to gain in life. Voyager continues on the journey home.
