Pressure by David Haig - Abbey Theatre

Pressure is based on true events that took place during World War II. It centres on the true story of James Stagg and the weather forecasts that determined the date of the D-Day landings as part of Operation Overlord. The personal and military stresses of Stagg, the tensions between the teams with different weather forecasts for the date of the proposed D-Day, and the events of the 72 hours leading up to D-Day are explored throughout the play.
