Life on Mars

Episode 5 (2x5)

:

The team investigates the abduction of a young woman and her daughter, who are being held prisoner by somebody who wishes the team to release a prisoner arrested on a murder charge a year ago. At the same time, Sam faces a life or death situation in 2006 when he thinks he has accidentally been given an overdose. As the deadline draws closer, Sam collapses into a deeper coma, leaving his colleagues to tackle the mystery on their own (Albeit using some of his earlier suggestions).
