Young detective Jonathan White (Channing Tatum) has achieved some success in his career. At this time, he was transferred back to the 118th block where he grew up. The 118th block is a community where poor people live and the crime rate is very high. One day, the district chief received an anonymous letter accusing a murder case many years ago. In the letter, Jonathan and his childhood friend Vincent Carter (Tracy Morgan) committed a murder together and faced the threat of being exposed. It is this unbearable secret that is destroying Jonathan's life and career step by step, and his wife Carrie White (Katie Holmes) and children are not spared.
