City by the Sea plot
"When you're searching for a killer... the last suspect you want to see is your son."
Vincent LaMarca is a respected Manhattan cop who returns to his neighborhood - Long Beach, New York - to investigate the murder of the notorious drug dealer Picasso. However, LaMarca is stunned when he discovers that the prime suspect in the case turns out to be his drug-addicted son Joey. The detective hasn't seen or heard from his son in years. After all, his painful divorce from Joey's mother had left an unbridgeable chasm all along. Once his superiors discover that LaMarca has a personal relationship with Picasso's suspected killer, he is removed from the case. But the cop can't watch helplessly and he goes looking for Joey himself.
