Ivan Ting Sin Boon (Gallen Lo) is orphaned at young age and was adopted by Ding Wing Bang (Paul Chun), the CEO of Ting Fung, a renowned jeweller in Hong Kong. His real name is Chung Tin Yun and his family died in a ship wreck when he was a child coming to Hong Kong. Ivan grew up knowing the business ethics his father went through as he built his empire, which included drug trafficking and illegal money interaction, but never got involved in the operations himself. No one knows of his true identity, not even his adopted mother and siblings.
On a trip to Perth, Australia, he meets Rachel Cheng Tian Lam (Jessica Hsuan). After a few incidents, they are brought together. As they are about to begin a relationship together, Ivan is called back to Hong Kong due to one of his father's old business partners requesting help. During this incident, he gets into trouble with the law; he crosses paths with an undercover police officer, Chung Shou Hong (Deric Wan) who is out to put and end to their illegal operations. Ivan is soonarrested for what seems like an illegal transaction between himself andhis father's old partner but in reality he simply gives money without actually taking the "goods". When he faces his case in court, the prosecutor is none other than Rachel. After clearing the misunderstandings, he manages to embark on a relationship with her.
However, in the middle of their relationship, Ivan is faced with moreand more crises. On one hand, he believes he killed Kai Chung (Kwok Fung) while trying to save his sister, Yan (Myolie Wu). On the other, heis constantly helping his family avoid legal prosecution due to their past. This puts a strain on their relationship.
Ivan's good friend, Sabrina Kwai Lai Fu (Anne Heung), who loves Ivan with all her heart, is constantly tormented by Hong Pak To (Shek Sau), his rival business partner. Pak To steals a precious crown meant from Ting Fung and she is forced to make a sacrifice of sleeping with him to get it back. Eventually, Pak To pushes her too far and she kills him. Asa result, Ivan decides to fully give up his relationship with Rachel because of obligation to Sabrina.
When his father dies, he is left with a the majority of the family fortune and is the principal stakeholder, making him CEO and Chair of Ting Fung. This upsets his second-uncle greatly. His brother Oscar, who studied in America, comes back to help in the family business despite initially hesitating and preferring to pursue a career in marine biology. Oscar accidentally hits someone with his car one day and their second uncle uses this incident to twist Oscar's mind into hating Ivan, initiating a power struggle between the two brothers that will lead to Ivan's true identity being revealed. Oscar is not pleased that a non-Ting member holds the ruling power in the company. Ivan agrees to allow Oscar to be the new CEO with a few stipulations.
Their second uncle continues to scheme, attempting to revert the company back into the money laundering scheme it used to be. Eventually Rachel goes out with Hong and he is revealed to be Ivan's brother who was thought to have died at sea. Sabrina leaves Ivan due to being constantly reminded of her time with Pak To. Soon after, Ivan and Hong reconcile, leading to Ivan and Rachel's increased interaction once again. She starts to understand his complex life and realizes why he made the choices he made and how it burdens him so. Ivan's personality makes her realize who she truly loved and she reconsiders her relationship with Hong. Meanwhile, Oscar is driven further and further down the wrong path by their second uncle.
Eventually, Oscar realizes the error of his ways and Ivan regains control of Ting Fung, exposing their second uncle. Once he realizes his late-father's dream for the company, he is free to pursue his relation with Rachel once again. In the end, Ivan and Rachel live happily ever after in Perth.
