Life on Mars - 2 ª Season

Sam is experiencing visions and pains that suggest that his life is in danger in 2006. At the same time, he runs into the younger version Tony Crane, a twenty-first century killer who Sam helped to convict. Sam comes to believe that Crane has escaped justice in 2006 and has come to wreak revenge on his comatose nemesis by torturing him...to death.

Sam receives messages from 2006 saying that his mentor, Glen Fletcher (Ray Emmet Brown) has died. He's shocked to meet a younger version of Fletcher in 1973, especially when he finds that his mentor has not yet grown into the man who he looked up to. Meanwhile, a prisoner's escape triggers Sam's suspicions about crooked dealings within the CID.

Manchester is beset with bomb threats that Gene readily pins on the IRA, but Sam's knowledge of history makes him doubt Gene's assertion. However, messages from 2006 and a grave mistake in 1973 are giving Sam reason to question his own judgment.

Sam and Annie investigate a world of suburban swingers' parties to investigate a murder.

A very ill Sam Tyler has reason to believe that he's been given an overdose of medication in 2006. While struggling with this, he's called into CID to assist with a troubling kidnapping case. With Sam not quite himself, it's up to the rest of the team to solve the case and save the lives of a mother and daughter.
