Flight Risk follows Captain Mike Lawson (Mark Wahlberg), a seasoned pilot haunted by a tragic past, as he faces his ultimate test. The story begins with Lawson reluctantly taking command of a commercial flight from New York to London. Unbeknownst to him, the plane has been targeted by a well-organized group of hijackers posing as passengers.

As the hijackers take control mid-flight, they demand Lawson follow a precise flight path, threatening to execute passengers if their orders are not met. Their ultimate goal is to crash the plane into a top-secret government facility in London as part of a larger conspiracy. FBI agent Evelyn Clarke (Michelle Dockery), working on the ground, uncovers that the hijackers are part of an international criminal syndicate seeking revenge for classified government experiments.

Lawson must navigate the hijackers’ demands while secretly plotting to outmaneuver them. Using his deep aviation knowledge and ingenuity, he disables their plan mid-flight, causing the aircraft to stall temporarily but recover in time to avoid catastrophe. Clarke coordinates with Lawson, providing critical intel and sending a rescue team aboard mid-air through an unprecedented skydiving operation.

The climax sees Lawson engage in a life-or-death struggle with the lead hijacker in the cockpit, saving the day at the last moment. The film ends with Lawson overcoming his past demons and being hailed as a hero, while Clarke vows to dismantle the syndicate completely.
