The first season of His Dark Materials follows Lyra (Dafne Keen), a seemingly ordinary but brave young woman from another world. Lyra's search for a kidnapped friend uncovers a sinister plot involving stolen children, and becomes a quest to understand a mysterious phenomenon called Dust.

As she journeys through the worlds, including our own, Lyra meets a determined and courageous boy called Will. Together they encounter extraordinary beings and dangerous secrets, with the fate of both the living --and the dead-- in their hands.

Season two of "His Dark Materials" begins after Lord Asriel has opened a bridge to a new world, and, distraught over the death of her best friend, Lyra follows Asriel into the unknown. In a strange and mysterious abandoned city she meets Will, a boy from our world who is also running from a troubled past. Lyra and Will learn their destinies are tied to reuniting Will with his father but find their path is constantly thwarted as a war begins to brew around them. Meanwhile, Mrs. Coulter searches for Lyra, determined to bring her home by any means necessary.

Season three will see Will (Amir Wilson), the bearer of The Subtle Knife, and Lyra (Dafne Keen), the prophesied child, travel through multiple worlds to find and protect each other.
