Genesis is about David Wilkins as a medical student who, after falling in love with Jayne, discovers she is involved in a quasi-religious cult run by the self-proclaimed Lord Seth. He drugs and kidnaps her to force her to have his baby because she looks like his sister. David rescues her but, unable to have Lord Seth prosecuted, kills him during the rescue, ‘rough justice’, not realising his actions have been noted by an MI5 agent who subsequently follows his career.

Sadly, David is unable to save Jayne from her cult-induced drug addiction and, to spare him, Jayne chooses to disappear without telling him that she is expecting his child. This comes back to haunt him twenty-five years later in Shadows of the Past.
