Every Move She Makes (1984)

Alison Berger has only recently moved from the country to take up a new job as a computer programmer and already her future looks promising, both professionally and personally. But, unbeknownst to Alison, one of them has become besotted with her. Against her better judgement, Alison agrees to a 'once only' date with Matthew Pitt and from that night on, her life becomes a nightmare.
