Driving in the heart of the Highlands, Edmond Murray receives a call from his ex-wife, in tears. Their 7-year-old son went missing from a campsite. Soon it becomes clear that the child was kidnapped and the parents give way to despair.
 
FUN FACT:  As with Guillaume Canet in the original film, My Son (2017), James McAvoy was not given a script and had to improvise all of his dialogue. All other actors knew the script and story, and McAvoy's reaction to the other actor's revelations were genuine. This was done to capture the authentic shock and surprise a parent would experience when dealing with a traumatic event.
