The People Next Door (TV)

Having moved into their new home, young couple Gemma and Richard are perturbed by noises coming from next door and suspect child abuse by their reclusive neighbors after a little boy wanders into their house. When social services produce no evidence they start to make recordings of their own but Richard is alarmed that his partner is becoming obsessive, delivering a toy containing a mini-cam in the belief that the boy is being kept in a locked room. He reluctantly agrees to accompany her in investigating when the family is out but they are caught and taken to the police station - where they hope to find out if their concerns are justified. - IMDb
