The gang targets Carver after he accidentally bumps into one of their members while walking home from buying alcohol. The youth demands an apology, which Carver gives. However, this minor encounter appears to be arbitrary - Carl later admits there was no specific reason for the targeting. The gang's harassment escalates from that point, possibly because they perceive Carver as an easy target or simply as a way to exercise power.

Carver mentors Jimmy because they share a similar loss - Jimmy's brother was murdered. While on a photography assignment at a local school, Carver meets Jimmy and recognizes the boy's grief. This connection gives Carver a sense of purpose outside his own mourning, as he channels his grief into teaching Jimmy photography.

Carver's marriage collapses because he becomes consumed by grief after his son's death in a hit-and-run. He descends into alcohol and drug abuse, unable to cope with the loss. His wife Rachel cannot watch him destroy himself and they divorce. Despite this, they continue visiting their son's grave together, showing their shared grief remains a bond.

Christina, Carver's girlfriend, moves in with him to support him during his difficult period. As a fashion model, she provides a sense of normalcy and stability in his increasingly chaotic life. However, her presence does not halt his self-destructive behavior, and she later becomes a victim of the gang violence targeting Carver.

The police cannot find evidence because Christina's attackers wore masks during the assault, obscuring their identities. Although Ed provides photographs from his research into local gang violence, there is no concrete evidence linking any specific individuals to the crime.

Ed, a tabloid journalist and Carver's friend, helps kidnap Carl because he is frustrated with the police inaction after Christina's rape. Ed believes taking matters into their own hands is the only way to get justice. However, Ed grows uneasy about the plan after speaking with Rachel at a party and rushes back to Carver's apartment.

Carver's son died in a hit-and-run, but Carl reveals a devastating truth during the kidnapping - Carver's son was a member of the gang and was involved in a dangerous daredevil game where children dodged oncoming cars. On the night he died, Carver's son was participating in this game, which caused the hit-and-run accident.

Carver injects Carl with a lethal overdose of heroin because Carl admits to beating Jimmy and reveals the truth about Carver's son's gang involvement.

Yes, Carl reveals that Carver's son was a member of their gang and participated in dangerous activities. Carl claims he knew Carver's son, who was involved in a daredevil game where kids dodged cars on the night he died. While Carver initially dismisses this, the revelation shakes his entire understanding of his son.

Carver calls for an ambulance because he experiences a moment of moral reckoning after injecting Carl with heroin. As the drug takes effect and Carl suffers, Carver realizes he has become what he hated - a person capable of murder. This act of calling for help represents his final choice between vengeance and redemption, though it comes too late to erase the horror of what he's done.
