This car accident is etched in Kelin’s memory forever. She remembered every moment, every cry that escaped from her lips and enveloped her in fear, pain, darkness... She remembered everything, but not the face of the stranger who saved her from the clutches of death when she was in the hospital in serious condition. Who is he? Who is the stranger who saved her? The more Kaelin thought about these questions, the more her mind became clouded. After a car accident, she began to notice some oddities and someone's constant presence, which gave her a feeling of security and at the same time danger.
