Golden Boy," is a drama about the meteoric rise of an ambitious cop who becomes the youngest police commissioner in the history of New York City, and the high personal and professional cost he pays to achieve it. As he's interviewed for a story about his career, Walter William Clark, Jr. (Theo James) flashes back on his hard-fought journey from street kid to the most powerful man in law enforcement. After only three years as a beat cop, Clark's heroics on the job make him bold enough to ask for and receive the unheard - of promotion to Homicide Detective, angering the members of his new department who are eager to see him fail. Clark's disappointed to be partnered with veteran Detective Don Owen (Chi McBride), a gruff lifer just two years shy of retirement. He would rather team with First Grade Detective Christian Arroyo (Kevin Alejandro), the alpha dog in the squad who's just as ambitious as Clark, but without a moral center. Arroyo's partner is Detective Deborah McKenzie (Bonnie Somerville), a tough third-generation cop and the only female detective in the unit. Also on the team is Detective Joe Diaco (Holt McCallany), well-connected with tremendous resources which Clark might find useful. Though laser-focused on moving up the ladder, Clark's soft spot is serving as the sole caregiver and supporter of his sister, Agnes (Stella Maeve), a teenager demonstrating increasingly dangerous behavior. Keenly observant and politically savvy, the Golden Boy bases his career decisions solely on his need to succeed as quickly as possible, and he'll find that his epic journey will be filled with consequences.
