After the shocking, Continent-altering events that close out season three, the new season follows Geralt, Yennefer, and Ciri who are faced with traversing the war-ravaged Continent and its many demons apart from each other. If they can embrace and lead the groups of misfits they find themselves in, they have a chance of surviving the baptism of fire and finding one another again.

As monarchs, mages, and beasts of the Continent compete to capture her, Geralt takes Ciri into hiding, determined to protect his newly-reunited family against those who threaten to destroy it. Entrusted with Ciri's magical training, Yennefer leads them to the protected fortress of Aretuza, where they hope to uncover more about the girl's untapped powers; instead, they discover they've landed in a battlefield of political corruption, dark magic, and treachery. They must fight back, put everything on the line - or risk losing each other forever.
