Intruder

Sam and his wife Rebecca Hickey enjoy an idyllic life in their custom-built West Country home, unaware that the peace they have found is shattered one night when two teenagers break into their residence. Sam's paranoid rage leads him to fatally stab Syed Khalil, who was trying to escape through a window at the time. The couple soon realize it was not self-defense and attempt to cover up the crime by planting a knife on Syed and staging the scene as if he had attacked them first. As they try to hide their involvement with the police, one of the people investigating them stands out: Karen Bailey, a "FLO" or family liaison officer whose conscience is triggered when she meets Syed's father. Her obsession with the injustice grows, leading her to uncover corruption within the investigation and even blackmailing Rebecca about what really happened. Meanwhile, Angela, their friend and guest, turns out to be an alcoholic loose cannon who may leak information about the truth. Sam and Rebecca both have secrets that affect them deeply. As their cover-up crumbles, they are forced to face their innermost psyches in terrifying revelations of a web of corruption involving Karen Bailey's boss. The investigation into Syed Khalil's death spirals out of control, revealing a sinister plot that threatens not only the Hickey family but also those around them.
