When Desmond Doyle finds his girlfriend dead in the bath, having cut her wrists, he is devastated. But there are inconsistencies with how suicide wounds would be inflicted and he quickly comes under suspicion and is arrested for murder. Though soon released, Detective Inspector Harry Kneebone is convinced of Doyle's involvement.

As they await the coroner's verdict, Doyle attempts some semblance of normality by returning to his job as curator for a new restaurant that will display original art. When he meets up with artist Gina Harding, he is deeply disturbed by paintings she has been strangely compelled to create in recent days. He recognises in them the likeness of his girlfriend's death scene. Can they shed light on Daphne's death, or is it all a bizarre coincidence?

As Doyle's grip on what is real and unreal becomes increasingly uncertain, a chain of events unfold that lead him to doubt his own sanity. Falling Slowly is a compelling and fast-paced psychological drama that questions the nature of perception and experience, as one man struggles to uncover a dark truth.
