In 'Reservoir Dogs', Tim Roth plays Mr. Orange. His character is a young undercover cop who infiltrates the gang of thieves. He has to maintain his cover throughout the chaotic events that unfold during and after the botched diamond heist. He is in a very tense situation as he tries to balance his loyalty to the police with the need to convince the criminals that he is one of them.
One key moment is when he gets shot during the heist. It sets off a chain of events as the other criminals try to figure out what went wrong. Another is when he starts to bond with Mr. White, which adds an emotional layer to his undercover role.
