Twenty years ago, Jiang He, codenamed "Uncle Snake", was framed by three partners and took three lives behind him, forcing him to flee far away from home. Twenty years later, Jiang He died of illness, leaving his son Jiang Shuo a black umbrella engraved with a silver snake and a line of words - Go to Guangzhou, Tianzi Wharf.
Jiang Shuo opened the umbrella and walked into the rain in Guangzhou. People in the whole street were avoiding him. Uncle Snake's old subordinate Guan Jiu waited for twenty years and finally found the new owner of this umbrella.
Three pieces of evidence, three traitors, and an old debt with interest.
