Lilly reopens the 1988 murder of a teen who died on his graduation day after being run down by an unknown driver. The probe is prompted after the victim's daughter, who was abandoned at birth and is now a teen herself, is confronted by a man who claims to be her real father and wants to take her away. Joining the investigation is Josie Sutton, a detective who transfers to the cold-case unit following an alleged sex scandal.

Lilly investigates the 2004 death of an 18-year-old woman who was killed in a frat-house fire.

Lilly reopens a 1978 case in which a young man was stabbed to death outside a theater where the slasher flick "Halloween" was playing. At the time, the unsolved murder was thought to have been committed by a copycat killer influenced by the film.

His mother believes that proposal led to his death.

Meanwhile, Valens believes a man who threw a woman into a river from a bridge may have killed Elisa as well.

The 1973 murder of a Vietnam prisoner of war who was slain seven months after he returned home is reopened after a box of POW bracelets with the victim's name on them turns up in the cellar of a drug house.

In 1988, a young man is gunned down on a highway after his car is hit from behind and a woman riding with him is wounded.

The investigation reveals that the woman and the married victim were having an affair and planned to run away with each other.

The 1968 death of an 18-year-old girl who apparently fell down a flight of stairs backstage at a debutante ball is investigated after her mother comes forward with new information. A local art dealer, who back in 1968 escorted the victim at the ball, is accused of killing his wife by pushing her down the steps. The mother believes it isn't a coincidence that both victims died in the same way. Lilly becomes convinced, too, but there isn't any evidence to prove it.

Lilly investigates the 2000 murder of a bank teller, who was gunned down during a robbery by thieves wearing Johnny Cash masks and carrying sawed-off shotguns, after the same bank is hit again by robbers wearing similar masks and equipped with identical weapons.

A rising female tennis player is strangled to death in her college dorm room in 1973 after defeating the school's top-ranked male player in a "Battle of the Sexes" fund-raiser.

Also, Vera's wife tells him that their 12-year marriage is over.

An actor appearing in a local production of "Cabaret" is shot and killed on opening night in 2002 outside of the theater. The case is reinvestigated after a gun, the same caliber used in the murder, is found in a dresser that was a prop in the play. The probe reveals that the victim, engaged to be married, may have been falling in love with his leading lady and that he made the mistake of standing up to the show's demeaning director.

A woman's body is found in a ravine on Christmas Day in 1929. Lilly decides to reinvestigate the unsolved crime after the victim's great-granddaughter comes in and asks for help in solving the murder.

As for the case, it's learned the victim had a baby out of wedlock and needed money to support the child.

The 1994 rape and murder of a 16-year-old girl is reinvestigated after a death-row inmate convicted of the crimes who is scheduled to be executed in three days calls Jeffries claiming that he's innocent.

The unsolved 1945 death of a woman reporter thrown in front of a train during an alleged robbery is reopened when new evidence suggests she was murdered by someone she knew.

The probe reveals that the doctor had a gambling problem and was broke. Also, Valens takes action when a suspected child molester is spotted in a park.

Lilly reopens the 2005 murder of a man who was a counselor to troubled teens at a rehab house. The victim was killed by a shotgun blast through his front door just two weeks before he was to testify in court about a murder he witnessed at the rehab house.
