Lifeline (2025) Plot Summary & Ending Explained

Steven’s journey ends with a shocking revelation: he has been dreaming or living in a constructed reality all along. Throughout the film, Steven believed he was a successful psychiatrist with a loving wife and a son named Jeff. However, as the story unfolds, it becomes clear that much of his life is a fabrication born from his trauma and memories of childhood abuse. The mysterious calls he receives, including the one from his younger self, serve as a metaphor for confronting buried memories and inner demons. When Steven tries to save Mary, a woman suffering from abuse, he succeeds temporarily, but the bigger picture reveals that reality itself is unstable and manipulatable.

As Steven delves deeper, he discovers that his memories have been altered. His relationships, his wife’s identity, and even his son turn out to be products of a distorted memory or a dream. The crucial moment comes when he recognizes that the entire world around him has shifted—his wife is no longer Vivian but someone named Huxley, and his son is called Tyler, not Jeff. These inconsistencies indicate that Steven is trapped in an illusion, possibly a coma or a multiverse of realities influenced by his trauma.
