Ending Explained

In the conclusion of Richard Linklater's film "A Scanner Darkly," the protagonist, Bob Arctor (played by Keanu Reeves), fully succumbs to the effects of the drug Substance D, which has split his personality and devastated his cognitive functions. Arctor, who was an undercover agent tasked with infiltrating the drug's distribution network, becomes one of its victims, losing his identity and the ability to distinguish his true self from his undercover persona, Fred. The film ends with Arctor in a rehab facility, having lost his memory and mental coherence due to the drug's effects. Unknown to the staff and Arctor himself, his placement in the facility is part of a larger plan by the government agency he worked for. They hope that he might lead them to the source of Substance D, as the farm where the rehab is located is suspected of growing the drug's raw materials.

He secretly collects a blue flower from the farm, which is the source of Substance D, and prepares to send it to his friends, hoping it might help expose the truth about the drug. The film closes on a note of bleak ambiguity, leaving viewers questioning whether Arctor's actions might spark any change or if they are just the futile efforts of a broken man.
