Wayne Lai is determined to make his own name in the business world and triumph over his father (Elliot Ngok), as a way of getting back for the many years of having to live under his tight control. Despite previous failures, Wayne is ready for another comeback with the help of Raymond Wong, Nancy Wu and Edwin Siu. They start up a mobile application company, with the intention of waging an all-out business war against Elliot. Ever since Wayne left home, his brother (Raymond Cho) has been cast aside by Elliot. His stepmother (Susanna Kwan) uses this opportunity to promote her son (Jason Chan) as the successor of the corporation and secretly works out a takeover plan. Facing repeated attacks from Susanna, Wayne fortunately receives the emotional support of his ex-girlfriend Maggie Siu and her autistic son (Fred Cheng). He also reconsiders his relationship with his father. Seeing Susanna's plot to take over Elliot's business empire, Wayne joins with his brother Raymond and step-uncle Power Chan to fight back. Unexpectedly, friends turn into rivals, while former foes become allies, making it difficult to distinguish the enemy in this dangerous dilemma.
