Synopsis :
Time was served for a crime he did not commit.
After ten years, can he discover the truth behind his father's murder?

Cheung Sing Hei (Cheng Kevin) is accused of murdering his stepfather and he is sent to the prison for 10 years. After being discharged from the prison, Hei decides to take revenge on his best friend and cousin Tong Lap Yin (Kwok Chun On). Yin works as a notary. He is an honest and trust-worthy gentleman who never blames Hei for his short temper and unreasonable accusation. He spends a lot of time to investigate Hei's case and help him find the real murderer. Hei and Yin used to be best companions but they fall out eventually because of deceit and trickery. What makes the matter worse is – they have fallen in love with the same woman.

Hei loses all his confidence after being sent to the jail unjustly. Lei Pui Ka (Mung Yo Yo), the reporter who visits him regularly during her voluntary services, manages to bring hope and joy to him again. Even though Ka appreciates Hei's character, she is deeply in love with Yin and she agrees to marry him eventually. However, Ka receives some anonymous letters continuously and these letters give her a great shock.
