Ambush(2001)

Ambush is an action film following a professional driver hired to transport an elderly man to a secret destination. When armed gunmen in a van intercept them, claiming the old man has stolen diamonds and swallowed them, the driver faces a split-second choice. He decides to help his passenger escape, triggering a high-octane chase and firefight. After evading the attackers and watching their van destroyed, the driver delivers the old man to a nearby town. When he asks whether the diamonds were really swallowed, the old man only smiles enigmatically and disappears into the crowd, leaving the driver—and the audience—wondering if he was played for a fool or helped pull off the perfect heist.
