《心冤》將以近5年幾宗極之轟動、香港人會記得的案件為重心，雖然是奇案的角度，但會用新的手法去拍，著重犯罪者及執法人員的心理。他強調這部劇很地道，是講香港的故事。

警与匪，从来都是正邪分明。《心冤》以曾经轰动一时的香港三大奇案——富家女绑架案、弒双亲碎尸案及警察宿舍灭门案为蓝本，讲述了破案无数的女探员宝飞凤（惠英红饰），面对突然人间蒸发的神探丈夫而卷入杀警事件，与铁面神探祁德胜（谢君豪饰）展开了正面交锋，一切行动都在祁德胜的监控之中。虽然表面上证据确凿，但宝飞凤却坚信自己的丈夫没有参与弑警案件。就在宝飞凤誓要将案件查到水落石出之际，香港却发生连串曲折离奇的命案，令两个原本因为杀警案对立的人不得不站在同一阵线，联手侦查一宗又一宗错综复杂、耐人寻味的香港奇案。

Inspector Bo Fei Fung is suspected of being involved in criminal activities and betraying the police force after her husband Lau Wai Yi mysteriously disappears and becomes a prime suspect of corruption as a police detective himself. Through a series of cases based on real high-profile crimes from Hong Kong, she has to prove her innocence to fellow detective Kei Tak Sing and solve the mystery behind her husband's disappearance.
