Jack Shephard is a gifted spinal surgeon who becomes the reluctant leader of the Oceanic 815 survivors after their plane crashes on a mysterious island. Defined by his compulsion to fix everything and everyone, Jack is the show's 'man of science,' locked in a long philosophical duel with the faith-driven John Locke.
Haunted by his relationship with his late father and his own controlling nature, Jack struggles to let go and trust the island's strange purpose. His arc carries him from desperate skeptic to, ultimately, a man of faith who sacrifices himself to save the island and his fellow survivors.
The series famously bookends with a close-up of Jack's eye — opening in the pilot and closing in the finale — framing the entire saga as his journey from denial to acceptance.
