The film is based on the book of the same name, which was co-written by the twins, along with Joanna Hodgkin. The film recounts the extraordinary story of Alex Lewis, who, at the age of 18, suffered a traumatic brain injury in a motorcycle accident that wiped his memory clean. His identical twin brother, Marcus, becomes his sole connection to the past, rebuilding his life by showing him photographs, sharing stories, and reintroducing him to his family and friends. This seemingly idyllic narrative of fraternal love, however, harbors a devastating secret. As Alex slowly re-establishes his life, Marcus omits a dark and painful chapter of their childhood. The true horror of their past is revealed only years later, transforming the narrative from one of selfless devotion to a complex examination of truth, memory, and the lengths one will go to protect a loved one.

The emotional core of the documentary is its raw and unflinching look at the human experience, forcing viewers to confront their own understanding of truth and forgiveness.

The Emotional experience

Tell Me Who I Am is not a film you simply watch; it is a film viewers can feel. The interviews with Alex and Marcus are incredibly intimate and candid, drawing one into their shared trauma and the heavy burden they carry. Viewers witness the emotional toll on both brothers, from Alex’s initial frustration and confusion to Marcus’s profound guilt and sorrow.

The documentary’s central conflict extends beyond the personal tragedy of the Lewis brothers, exploring broader themes of family dynamics and the construction of personal identity.

Out of Netflix's various documentaries, this has the most impactful scenes that explore the profound connection between memory and identity. For Alex, his identity is not a product of his own memories but a story built for him by his brother. The film asks a fundamental question: Who are the people without their memories? The film examines the intricate and often flawed dynamics within families, showing how shared experiences, even traumatic ones, can forge unbreakable bonds. The documentary is a poignant reminder that family is not just about blood; it is about the stories one shares, the secrets one keeps, and the unconditional love that can endure the most painful truths.
