Episode 2 of "The Witch and the Beast" begins with an ominous opening, where a woman's peaceful journey home is disrupted by a dark presence, leading to a fateful encounter that ends in her distress and hints at a sinister force at play.

The narrative then shifts to Guideau and Ashaff as they take on their latest assignment to capture a magical beast without harming it. Their differing approaches and priorities become apparent, especially when Guideau's disinterest surfaces due to his lack of connection to witches.

During their lunch break, tensions rise between the two as Guideau voices dissatisfaction with their recent missions and questions Ashaff's understanding of her motives. Their conversation is interrupted by a new task that leads them to the home of an elderly woman. There, Ashaff demonstrates her magical abilities and teaches Guideau a lesson about the importance of their varied work.

The plot intensifies when a black letter appears, pointing to a case deeply tied to witchcraft and leading the duo to Hayden, a town plagued by grotesque serial murders. The introduction of Kiera Haines, a mage working with Hayden's police force, opens a dialogue about the killings, resulting in a collaboration between the police and the Order.
