Black Out

Jung-woo arrives at a warehouse where the incident happened and falls in great agony over the memory of that day; hearing about her mom's accident belatedly, Jung-woo tries to determine the cause while everyone in the village distrusts her.

As Jung-woo investigates her mother's accident, Detective Sang-cheol suspects her upon learning her identity; Ha-seol, interested in the village's past incident, focuses on a strange bone she found.

After two teenage girls are murdered, the only suspect is their friend, but he doesn't recall a single memory; after he serves 11 years in prison, another murder flips the village.
