S02E08: The Finale

Bringing down Gene Hunt and his unlawful policing methods seems to hold the key for Sam's return to the present day.

Sam finally asks Annie to spend one night in his company. Her response suggests she's a bit of a slapper, but in the more literal sense of the word.

A pivotal scene with Sam and Frank Morgan takes place in a graveyard. Several tombstones shed some light on what might be going on.

Gene goes on a very dangerous undercover mission, using a railway set and toy soldiers to help visualise the cunning plan.

Ray owes Sam for indirectly setting him up with a nice nurse.

As for the ending, you'd better tune in next Tuesday night on BBC One, although a more recent David Bowie single than 'Life On Mars' offers a big hint, if you delve into his early '90s material.
