Cold Case is an American investigative television series that focuses on police procedures involved with cold homicide cases through the fictional Philadelphia Police Department. Cold Case full episodes were first aired in 2003 and they continue to gain popularity among viewers of all ages.

Each Cold Case video begins with a flashback that establishes the year of the original crime and some of the major players in the story. Cold Case full episodes are sparked by the discovery of new evidence or the stepping forward of a previously reluctant witness.

Main character Lieutenant John Stillman is played by John Finn while Kathryn Morris plays Detective-In-Charge Lilly Rush. Morris' character's past is frequently revisited in Cold Case clips as the daughter of a poor, dysfunctional alcoholic mother. Detectives Scotty Valens (Danny Pino), Will Jeffries (Thom Barry), and Nick Vera (Jeremy Ratchford) fill out the dramatic aspects of Cold Case full episodes as the investigations, as well as their personal lives, are examined.
