Brotherhood

In Brotherhood, Liu and Keung are portrayed as competent constables and good partners. When Keung is dismissed from the force due to a minor mistake, he finds himself in financial trouble and resorts to crime. Liu tries to assist his partner but soon finds himself ensnared in a web of internal investigations.

The film explores themes of loyalty and betrayal, especially when Liu's younger brother is assigned to capture Keung's gang. This complicates Liu's position as he must confront his loyalty to his partner versus his duty as a police officer. The tension escalates as the gang poses a threat to both Liu and Keung, culminating in a gripping climax that tests their bond and resolve.
