Episode 1

A year after witnessing a traumatising attack in her neighbourhood, Hannah, a young wheelchair user, witnesses a copycat attack on her area's CCTV system, in the only part of the estate not covered by cameras. The attacker enters the area with an unknown woman but emerges alone. What happened to the woman? Hannah believes she was murdered but there is no evidence of a crime. She feels thwarted by Tony, the washed up and possibly corrupt police detective on the case, but she perseveres and soon finds her own life in danger trying to investigate what really happened in the Blind Spot.
