Washington, D.C., Police Chief Jack Mannion, runs a modern-day "Untouchables" team to patrol the most crime-ridden, drug-infested streets in his city.

While investigating a museum heist, Debreno and Cahill find the suspect in the museum but not the stolen Picasso painting.

When Mannion decides to fire a popular and respected police commander whose recent performance statistics are below average, pressure from within the precinct and from the community forces him to rethink the decision.

Chief Mannion is forced to knock heads with CIA officials to find out what they know about a murder victim.

An anonymous letter and a priest spur Mannion and his team to try to stay the execution of a death row inmate wrongly accused of murder.
