Alex has caught a hospital infection and knows the doctors in 2008 are losing hope for her. Feeling ill, weak and estranged from Gene, she is terrified that time is running out for her to get home. But when an informant is tortured and killed, Gene is convinced that a major blag is about to happen and wants CID to fire on all cylinders to stop it. Alex desperately needs Gene's help, but to get it would involve telling him the truth about who she is and where she is from, the reality of which is surely too big for him to comprehend. Gene grows increasingly suspicious of Alex's behaviour, and at the same time his head is turned by Jenette, an attractive woman whose uncomplicated nature and simple belief in him offers him everything Alex cannot. A wedge develops between Alex and Gene that threatens to rip the whole team apart, and their relationship is put to its toughest test yet in a heart-stopping showdown.
