After surviving a near-fatal accident, track coach and mother Dana awakens in hospital, paralysed and imprisoned in her own body. Whilst struggling to regain control of her life, Dana is confronted with a vindictive spirit; a terrifying presence called Nails, whom she is convinced exists inside her hospital room.

Faced with scepticism from her husband, doctors and the staff, and believed to be suffering from a mental breakdown, Dana is left struggling to keep her grip on reality as the targeted attacks grow increasingly violent.

Nails is out in cinemas from Friday.
