Dark Rising: Bring Your Battle Axe (2007)

In a desperate attempt to save his fizzled-out relationship, Jason organizes a camping trip with the help of his best friends: Ricky, a ladies' man who shoots "1-900" commercials, Marlene, a long-time friend and yoga instructor, and Renee, a book worm with a knack for witchcraft.

Each for their own reasons, they convince Jasmine to join them for a weekend of fun in the sun. Unknown to the group, Renee has been having recurring nightmares of Summer Vale, a girl from their town, who disappeared over twenty years earlier. Renee decides to contact Summer's spirit during the camping trip. Also unknown to the boys, Jasmine and Marlene have become a hot item. They join in the fun and humor Renee's interest in magic.

Using the Book of Shadows, which she received from a mysterious bookkeeper, Renee chants a translated phrase. This opens a portal, and a Kellipoth demon enters, killing Marlene and biting Jasmine. Summer Vale is also transported back. She has lost her memories and is now a demon warrior princess.

Jason and Summer form an uneasy bond. They decide to reopen the portal, to return the demon to Dark Earth.

The Kellipoth bite infects Jasmine, making her a member of the Kingdom of Shells -- demon-like beings without a soul. Jason kills Jasmine but it is too late to save his best friend, as Ricky also succumbs to the Kellipoth. In the ferocious battle, Summer, Jason, and Renee manage to open the portal. Summer kills Demon-Ricky, the Kellipoth breaks Renee's neck, and Jason and Summer force the Kellipoth back through the portal. Jason makes the heroic sacrifice of entering the portal with the Kellipoth, allowing Summer to remain on Earth.

Reintegrating proves difficult for Summer. She can only find work as a model for "1-900" commercials. But her misery is brief. Jason, dressed as a Demon-hunter, returns for her help against an army of Kellipoths. At the bleakest point, the Agency offers help.

Caught in the imminent battle for the Earth’s future, Nathan joins with Summer Vale, a super soldier with Demon DNA who is dealing with her own clouded past. The two, along with Nathan’s sister Gwen and Summer's sidekick Bulo, try to unlock the mystery of the Tether and fight to protect the world from a Demonic army.
