The story begins with a supermarket arson case, where the 24-year-old suspect caused five deaths and twelve injuries. This case became the first case to be sentenced to death after the implementation of the national judge system.

The fire also burned out the fate of six families, which were missed and involved with each other. They carried their own life stories across 20 years, revenge, betrayal, hurt, fall, and salvation. After a random murder accident, where will fate bring these six families?
