The crew is on the way to rendezvous with Moya. After ingesting a concoction of Noranti's they stop for a break on a planet. Rygel is captured and entombed in amber by raiders.
When stopped off on a planet, Rygel leaves the rest of the group and is caught in an unbreakable orange substance while stealing treasures he discovers in a cave. When D'Argo, Crichton and Noranti go looking for him, the cave seals them in. Two huge grunts appear who have protective armor which protects them from weapons fires.
After a forced landing, the crew is divided by an elaborate trap that leaves Crichton, D'Argo, Noranti and Rygel underground in a lava-filled system of caves. Chiana and Sikozu are left outside, trying to re-activate D'Argo's ship. Inside, Crichton and the others are hunted down by mercenaries who are led by a monster impervious to the fiery lava.
