The film centers around a mysterious and enigmatic man named Prot (played by Kevin Spacey) who claims to be an extraterrestrial from a distant planet called K-PAX. Prot is found wandering in Grand Central Terminal in New York City, and he is taken into custody by the authorities after exhibiting unusual behavior.
Prot is taken to a psychiatric hospital, where he is placed under the care of Dr. Mark Powell (played by Jeff Bridges), a psychiatrist who is skeptical of Prot’s claims of being an alien. However, as Dr. Powell delves deeper into Prot’s background and behavior, he becomes intrigued by the possibility that Prot may be telling the truth.
Prot exhibits a deep knowledge of astronomy, physics, and other scientific subjects that seems beyond the capabilities of an ordinary human. He also displays unusual abilities, such as the ability to see ultraviolet light and the ability to heal wounds with his touch.
As Dr. Powell conducts interviews and gathers information about Prot, he uncovers evidence that seems to support Prot’s claim of being from another planet. However, Dr. Powell remains skeptical and seeks to uncover the truth behind Prot’s identity and origins.
Meanwhile, Prot forms bonds with his fellow patients at the psychiatric hospital, offering them comfort, guidance, and wisdom. He encourages them to confront their own personal demons and overcome their struggles, inspiring them to find hope and meaning in their lives.
As Prot’s scheduled departure date approaches, Dr. Powell becomes increasingly desperate to uncover the truth about Prot’s identity. He conducts further research and interviews Prot’s family members and associates, hoping to find evidence that will either prove or disprove Prot’s claims.
In a climactic twist, Prot reveals the truth about his identity to Dr. Powell in a heartfelt and emotional conversation. He explains that he is actually a human named Robert Porter who is suffering from a severe dissociative disorder. Prot created the persona of an alien to escape from the pain and trauma of his past.
As Prot prepares to leave the psychiatric hospital and return to his former life, Dr. Powell realizes that Prot’s delusions were a coping mechanism to help him deal with his own personal struggles. Although disappointed that Prot is not an alien, Dr. Powell is inspired by Prot’s resilience and courage in facing his demons.
