A plot twist is an unexpected change in the direction or outcome of a story, often surprising the audience. It can occur in various forms, such as revealing a character's true identity or altering the perceived motivations behind their actions. Plot twists are commonly used in literature, film, and television to enhance storytelling and keep the audience engaged. These twists can serve multiple purposes, including deepening the narrative, challenging assumptions, or providing a fresh perspective on the plot. Effective plot twists often rely on foreshadowing, where subtle hints are dropped throughout the story, allowing for a satisfying revelation when the twist occurs.
