When Peter checks on his 82-year-old father at home one morning as normal, he finds the house empty. Suffering from advancing dementia, Archie has vanished – leaving no sign of where he might be. As an ex-paratrooper, Archie has been physically fit all his life and has been struggling to accept his increasing fragility. Dementia sufferers are known to travel vast distances when they disappear, and a full-scale land and air search is launched to find Archie.

But as hours tick by without so much as a single confirmed sighting, and a neighbour comes forward with CCTV of potentially suspicious activity at Archie’s home address, the police begin to suspect foul play.
