When a deadly virus breaks out on a commercial flight, Dr. Emily Carter, a virologist, and Captain Mark Reynolds must work together to contain the outbreak and keep the passengers alive. As governments around the world refuse to allow the plane to land, fear and panic spread faster than the virus itself. Trapped at 30,000 feet, the passengers must confront their deepest fears and make impossible choices. Set against the backdrop of a claustrophobic and high-stakes environment, this is a story of survival, humanity, and the lengths we go to protect those we love.
