Escaping the Paxons caused damage to the Cartegos that requires more extensive repairs than Vel and Shen can perform in space. To access the damage, they need to set down in an atmosphere. To reach a planet with an atmosphere, they need Nya to open a portal, and the Starfire entities have the perfect location.

While the ship undergoes repairs, L'Ni accompanies Nya on a journey into a cave on Karam Three to find the shard left there. However, the wildlife is protective of their world and attack ferociously to defend their territory, driving Nya and L'Ni deeper into the abyss of the cave.

The situation is no better for their friends. While Nya and L'Ni are trapped within the darkness, their friends must make a difficult decision.

Not all is what it seems on Karam Three.
