A young switchboard operator tries to foil a kidnapping plot in the On The Line trailer

It’s 1964 and 24-year-old switchboard operator Agnes (Victoria Lucie – The Devil’s Machine) passes time listening to phone conversations as she connects peoples’ calls in the Channel Islands. However, things take an unexpected turn when she receives a panicked call from Shirley (Harriet Walter), an old woman suffering from dementia who suggests that she’s been kidnapped.

Alerting the police and collecting information from various callers, it doesn’t take Agnes long to deduce who the kidnapper is. As she assists the police in tracking him, things become more and more complex.

This gripping feature is brimming with suspense and mystery and with its powerful one-person premise, you’ll get hung up On the Line.

Oliver Pearn (Napoleon, Lord Of The Rings: Rings Of Power) makes his directorial debut in this impressive film that also stars Dame Harriet Walter DBE (The Young Victoria, Sense and Sensibility, The Last Duel, Succession) and Royce Pierreson (Line of Duty, The Witcher), whose familiar voices have a powerful impact.

The film is set for its UK premiere on 22 January courtesy of Miracle Media.
