In Nova City, Jace and his team are chosen as Frequency Guardians, protecting humanity from Abyss Beasts—mysterious creatures born from human emotions. But Ornn, the creator of the network, has a radical plan: erase human emotions completely to eliminate conflict.
Jace and the Guardians refuse to let that happen. Instead of destroying emotions, they choose to accept them and find a way for humans and the Abyss Beasts to live together in peace.
