In a bustling city with turbulent undercurrents, six people with different backgrounds gathered for different reasons and formed a folk suspense reasoning team. While solving a series of complicated social cases, the team repeatedly uncovered the darkness and light deep in human nature. Not only do they have to face perverted serial killers, trafficking and fraud syndicates, government-business collusion and other sinister forces, but they also have to face their own shadows, growth trauma and internal crisis of trust. Every pursuit of the truth is a collision between reality and conscience, and it is also the process of members recognizing themselves, mutual redemption and betrayal. When an old case that has been missing for many years comes to light, pulling six people into a huge whirlpool of conspiracy, the team begins to make the final choice between justice, friendship, and the truth. In the end, they used blood and wisdom to piece together the answer to the real world.
