The CW has officially announced the premiere date for their four-hour event miniseries “Labyrinth.” The series will air over two nights beginning on Thursday, May 22 and finishing up on Friday, May 23. “Labyrinth,” adapts Kate Mosse’s New York Times best-selling novel and features a multi-national and award-winning cast, including John Hurt, Sebastian Stan, Jessica Brown-Findlay, Vanessa Kirby and Tom Felton.

Filmed on-location in the medieval town of Carcassonne in southwest France and Cape Town, South Africa, the historical miniseries jumps back and forth between modern and medieval France as it follows the lives of two women who are separated by centuries, but united in their search for the Holy Grail.

In Carcassonne, France, in the year 1209, 17-year-old Alaïs (Brown-Findlay), is given a mysterious book by her father; a book which he claims contains the secret of the true Grail. Although Alaïs cannot understand the book’s strange words and labyrinth symbols, her father instructs her to protect the book no matter what happens to him. Alaïs realizes that her destiny lies in keeping the secret of the labyrinth safe. Eight centuries later, at an archeological dig in the French Pyrenees, a young volunteer named Alice Tanner (Kirby) discovers two skeletons in a forgotten cave. Puzzled by the labyrinth symbol carved into the rock, she realizes she’s disturbed something that was meant to remain hidden. Somehow, a link to a horrific past – Alice’s own past – has been revealed.
