When an air traffic controller (TJ Herbert, The Cutting Room) is suspended following a serious in-flight incident, his journalist wife Helen (Georgina Sutcliffe, Age of Heroes) suspects that there’s a deeper angle to the story. With the aid of a reporter colleague (Rita Ramnani, The Hunt for Gollum), Helen embarks on an investigative journey that leads to JaspAir Airlines…and reveals a disturbing succession of cover-ups regarding air quality on flights dating back to 1954. JaspAir owner Sir Charles Jaspar (Nicholas Day, The Wolfman) has tasked his company’s CEO (Mark Dymond, Die Another Day) with keeping his business and his wife Maggie (Marina Sirtis, Star Trek: The Next Generation) out of the impending media storm by any means necessary. But with pilots and passengers at risk, Helen and Natasha risk their jobs, reputations, personal relationships and safety to expose the truth behind Flight 313.
