Tense drama telling the story of the kidnap of a child in 1950's London. Lee (David Knight) and Sue (Julia Arnall) Cochrane are a happily married American couple living in London with their 18 month old son Simon. Their idyllic lifestyle is shattered when one day the family nanny takes Simon out for the day and briefly leaves him unattended in his pram outside a local shop. On her return the nanny finds that Simon has been abducted. Scotland Yard, led by Inspector Craig (David Farrar) and Sergeant Lyel (Anthony Oliver), are soon on the trail of the kidnappers and their pursuit leads them down a path of danger and intrigue. The film makes great use of locations throughout London and the South East of England and the slice of life in 1955 is fascinating.
