Caroline adopts a quiet, unnervingly obedient dog named Bishop, believing she is offering him a second chance. Soon, her home fills with whispered sounds, moving lights, and the sense of being watched. Bishop’s loyalty turns possessive, his presence impossibly heavy, his silence hiding something inhuman. When Caroline finally flees, she vanishes without a trace. At the shelter, a new dog appears—calm, well-behaved, and waiting. This time, her name is Caroline.
