Present day with flashbacks to the high school years

The film moves between the immediate present and vivid reminiscences from Fred’s teenage years. Time feels malleable as Fred learns to travel across multiple timelines and glimpse possible futures.

Present-day settings like Fred’s office and the apartment lobby ground the narrative as it fractures into visions of other timelines. Fred and Cindy’s journeys also take them to distant locales such as the Middle East and a Mediterranean villa during their travels through alternate lives.

4 major themes

Flashback Meaning: Themes & Message Explained

What is Flashback (2021) really about? The emotional, social and philosophical themes the film keeps returning to, its symbolism and the message beneath the surface.

  • Time Perception

    The film centers on how memory can bend or break the perception of time. Fred’s visions blur past, present, and possible futures, suggesting that linear time is a controlled illusion. An invasive lifeform is revealed as enforcing a fixed timeline, while the merc drug offers a temporary escape into the full spectrum of timelines.

  • Memory & Trauma

    Fred’s fragmented memories reveal trauma from past actions and relationships. The narrative uses surreal imagery—mouths, visions, and echoes—to illustrate how memory can trap or liberate a person. The hospital, the lobby, and the club become sites where memory is reconstituted.

  • Mercury Drug

    Mercury, the drug at the center of Fred’s high school years, acts as a catalyst for time travel and altered perception. The substance unlocks temporary freedom from linear time, enabling Fred and Cindy to live multiple lives. Its dangers are shown through memory turmoil and the risk of losing control.

  • Love Across Timelines

    Fred and Cindy form a bond that traverses multiple lifetimes, suggesting that love can persist beyond time’s constraints. Their relationship is both a beacon and a burden as they navigate different worlds. The film uses their connection to anchor personal stakes amid the complexities of time travel.
