Bobby also learns that his colleague and good friend Matt Yeung is Jeannie’s ex-lover. To guide her back to the right path, Bobby and Matt target the brothers Joe and Pierre. Bobby and Joe’s values are different and each has their own interpretation of justice. When the two men meet, a battle of wits is quietly triggered.
