Batman Chronicles The Gauntlet (1997)

Dick Grayson has been training for a very long time, and Batman is giving him a final exam before he's allowed to go out on patrol as a crime-fighter. The challenge is that he will be given a six-hour headstart at dusk, and then Batman will hunt him down and try to find him within city limits... if he can make it until sunrise without being caught, he passes. Dick ventures out into Gotham City dressed as Robin for the first time, and quickly finds himself embroiled in a criminal plot that he must stop while evading his mentor and many gangsters all across the city.
