While on patrol duty, EU sergeant Ling Sun-fung and her team are called to assist a criminal chase. A gun battle erupts and Sun-fung loses her father, who dies from a stray bullet to the head. Sun-fung continues the pursuit, but a strange natural phenomenon suddenly turns her away, taking her back to April 1—three days prior to the incident. Realizing that she has travelled back in time, she uses this opportunity to save her father's life. Village chief "Ditch", an informant for the ICAC, discovers Sun-fung's special ability and teams up with her to investigate a corrupted cop. Unfortunately, their persistent disruption to the timeline causes severe butterfly effects, with unsettling consequences.

Apart from succeeding his father as the owner of the social club, Hau Tak-sze is also a mediator, smoothing things out with unconventional measures for people from all walks of life. Due to a divorce case, he gets to know Mo Sui-yee, who is in the process of divorcing her cheating ex-husband. Through Sui-yee, Tak-sze also becomes acquainted with her sister, cousin, and co-worker. But just as they are becoming close, Sui-yee's ex-husband reappears, and their lives and relationships are driven to the brink of destruction...

Neurosurgeon Cheung Yat-Kin marries fellow doctor Fan Tze-Yu and the two are happily living together, expecting their first child. However, when Tze-Yu is diagnosed with a tumour, her pregnancy becomes medically unsafe and, much to her dismay, Yat Kin doesn't want her to go through with childbirth. This causes a dangerous rift between the two, one that love alone can't bridge. But before the once-happy couple can focus on their marital problems, Yat-Kin also has to contend with pathology specialist Lok Man-Sang, a new arrival to the hospital who simply cannot go without disagreeing with Yat-Kin, and who also gets involved with Heung Chin-Yi, an internal medicine doctor nearly 20 years his junior with her own heartbreak to deal with. Between an unwanted power struggle, the slow disintegration of their marriage, and the small matter of saving lives, Yat-Kin and Tze-Yu have to figure out how to bring their flat-lining marriage-and love-back to the operating table.
