Physician Pei Yuming held a family dinner for his third wedding anniversary. All his relatives and friends gathered together, but everyone died tragically of potassium cyanide poisoning. He was the only one who survived and was identified as the number one suspect by the police. He is trapped in a strange time and space loop, traveling back and forth to the day of the crime and constantly reviewing the truth. Cheating, gambling debts, pig slaughtering plates, and secret affairs have been exposed one after another. His wife, best friend, brother, and father all have hidden secrets, and everyone has a motive for the murder. Multiple reversals expose the evil of human nature layer by layer, and endless reincarnations are just to uncover the real murderer hidden among the loved ones. No one in the family is truly innocent.
