Aunt Danny, who is confined to her luxurious mansion due to a lung condition, lives amidst a swarm of cats, heightening Wylie's anxiety.

With each step deeper into the mansion’s shadows and secrets, Wylie and Kassia move closer to fulfilling their plan, but at increasing personal cost. The tension mounts as loyalties shift and hidden motives come to light, driving the narrative towards an unpredictable climax.
