In this 1970s crime thriller, we follow Miles Cullen, a shy bank employee who becomes a cunning thief after discovering a robbery plan. Miles' quiet life transforms when he learns that a dangerous criminal has devised a sophisticated heist at his bank. Instead of being a victim, Miles decides to take matters into his own hands and makes off with a substantial amount of cash, hiding it to ensure no one sees him.
However, his simple plan quickly complicates when the thief, a charismatic and violent criminal named Harry Reikle, realizes that something is amiss. With the police searching for the original thief and Miles attempting to keep his double life under wraps, an intense game of cat and mouse unfolds between the two men. As the tension escalates, Miles is forced to transform his introverted character into a bolder and more cunning one, as he tries to survive not only Reikle's wrath but also the intricate web of deceit he has entangled himself in. With unexpected twists and a haunting atmosphere, this film explores the boundaries of morality, greed, and what it truly means to be a "silent partner" in a deadly game.
