Funeral director Lin Wan discovers that seven bodies all have the same countdown tattoo on their wrists. On the seventh day, she receives the body of her husband, Zhou Zheng. His tattoo shows he has only six days left in his “false death” period. A mysterious figure forces her to take part in the “Redeemer Game”: all seven people faking their deaths are connected to a secret suicide case, and Lin Wan must identify the one innocent person before the countdown reaches zero to obtain an antidote. As her husband's past as a silent accomplice is laid bare, she is driven to the brink, torn between saving the man she loves and bringing the guilty to justice. The truth revealed at the end will redefine redemption and its cost.
