Ex-soldier Lin Chuan becomes CEO Su Xiao's bodyguard to fund his sister's surgery, only to accidentally activate the 'Doomsday System' hidden in her necklace—suddenly, a bright red '72 hours until alienation outbreak' countdown pops up, and he can see 'alienation warning red lines' on ordinary people. Worse, the system issues a mandatory task after binding: 'Protect Su Xiao to get the anti-alienation vaccine within 24 hours, or your sister’s heart stops on the operating table'! Lin Chuan deals with the system's weird punishments (like suddenly weak legs that make him fall into Su Xiao's arms if he fails a task) while fighting gangsters who want the vaccine. But he discovers Su Xiao has long been infected with the alienation virus—she hid her illness to sacrifice herself and destroy the vaccine's source! When the system countdown hits zero, Lin Chuan has to choose: save his sister, or save the world? And is the 'doomsday' just a bigger trick by the system?
