Barrister JJ Kam (Michael Tse) and Director of Public Prosecutions Chris Fong (Tavia Yeung) used to be cohabiting lovers, but ended up separating due to a failed marriage proposal. Fate has it when JJ makes a job transition to take a position of Prosecutor, resulting in the two working under the same roof once again. With their distinctly different approaches in handling cases, plus the interference of a new secretary (Grace Wong), the already severe crisis in their relationship has been pushed to the edge to an nonredeemable state. As each of them is hesitating over their future, a murder case involving a wealthy businesswoman Pong Tit-sum (Alice Chan) makes them go through an arduous and fierce journey all together.
