Sarah Jefferson (Ormston) is happily married to Andrew. They have two children: Katrina (11) and Michael (9). Sarah is being stalked – but does not know it. Her stalker Nigel (Savin) is a sinister and intelligent loner. He has a command of both forensics and electronics and a pathological need to control. Sarah works as a florist. Nigel buys flowers each day, only to destroy them, revealing his true psychopathy. Using his skills to execution his crimes, Nigel’s control of everything extends far beyond Sarah to include her family and the police. Nigel plans and attention to detail leaves little doubt in people’s minds that Sarah and Andrew’s relationship was in trouble. So compelling is Nigel’s manipulations that even Sarah and Andrew doubt each other and Andrew is pushed to the edge. This in turn leaves him vulnerable to exploitation.
