Former SWAT tactics instructor Shen Jin was framed by the Egret Society and jailed for five years for leaking secrets. After being released from prison, he became a "mad dog" thug in the underground boxing ring. During a fight to the death on a rainy night, he unexpectedly awakened the power of "predicting death three seconds in advance" and received a mysterious photo, which pointed out that the mastermind of the unjust case was his former teammate Zhou Mingxuan.
In order to clear his grievances and avenge the sacrificed team members and their families, Shen Jin followed the clues and was involved in a more deadly conspiracy: the homeless old ghost was brutally silenced after delivering the certificate. The metal plate "LWQ" pointed to Lin Wanqing, the former psychiatrist who was paranoid and in love with him - she was actually a core member of the Egret Society and planned a series of murders to take him as her own.
Wanted by the police, betrayed by his brother Chen Mo, and pursued by the Egret Society, Shen Jin relied on his supernatural powers and ruthlessness to fight back in desperate situations. From underground boxing rings to charity dinners, from abandoned coal yards to mental hospitals, this mad dog crawled back from hell to fight against the entire dark organization alone, vowing to uncover all the truth and make all betrayers and perpetrators pay with blood!
