Season 1

Legion, based on the Marvel Comics by Chris Claremont and Bill Sienkiewicz, is the story of David Haller (Dan Stevens), a troubled young man who may be more than human. Diagnosed as schizophrenic as a child, David has been in and out of psychiatric hospitals for years. Now in his early 30s and institutionalized once again, David loses himself in the rhythm of the structured regimen of life in the hospital: breakfast, lunch, dinner, therapy, medications, sleep. David spends the rest of his time in companionable silence alongside his chatterbox friend Lenny (Aubrey Plaza), a fellow patient whose life-long drug and alcohol addiction has done nothing to quell her boundless optimism that her luck is about to change. The pleasant numbness of David's routine is completely upended with the arrival of a beautiful and troubled new patient named Syd (Rachel Keller). Inexplicably drawn to one another, David and Syd share a startling encounter, after which David must confront the shocking possibility that the voices he hears and the visions he sees may actually be real. A haunted man, David escapes from the hospital and seeks shelter with his sister Amy (Katie Aselton). But Amy's concern for her brother is trumped by her desire to protect the picture perfect suburban life she's built for herself. Eventually, Syd guides David to Melanie Bird (Jean Smart), a nurturing but demanding therapist with a sharp mind and unconventional methods. She and her team of specialists - Ptonomy (Jeremie Harris), Kerry (Amber Midthunder) and Cary (Bill Irwin) - open David's eyes to an extraordinary new world of possibilities [3].

Season 2

Syd led David to "Melanie Bird" (Jean Smart), a demanding but nurturing therapist who heads a team of specialists - "Ptonomy" (Jeremie Harris), "Kerry" (Amber Midthunder) and "Cary" (Bill Irwin) - each of whom possesses a unique and extraordinary gift. Together, they helped David to recognize and harness his hidden powers. With their support, David finally unlocked a deeply suppressed truth - he had been haunted his entire life by a malicious parasite of unimaginable power. Known as the "Shadow King," this malevolent creature appeared in the form of David's friend "Lenny" (Aubrey Plaza), but is actually an ancient being named "Amahl Farouk." In an epic showdown, David and his friends battled his demon, ultimately forcing it from David's body. Unfortunately, Farouk found a new host - Melanie's husband "Oliver Bird" (Jemaine Clement) - and escaped. Just when they thought they'd earned a moment of respite, a mysterious orb appeared and took David away to an unknown place. With David and Oliver missing and Farouk on the loose, the team forms an unlikely alliance with their former enemy "Clark" (Hamish Linklater) and his well-funded government organization, Division III. Meanwhile, Amahl Farouk (Navid Negahban) is on a new path to attaining infinite and world-ending power.
