Chang Lee was a teenage hoodlum in San Francisco Chinatown. His friends were all gunned down by a rival gang when their games went too far. Chang Lee was saved by the TARDIS materialising in front of him. When The Doctor was shot instead he called an ambulance and stayed with him to the hospital but when he was told The Doctor was dead he panicked and ran off with his personal effects. He found his way into the TARDIS but had been followed by The Master and was tricked into doing his bidding. Chang Lee realised too late that The Master was the evil one and The Doctor good. The Master killed him by breaking his neck but after he had been defeated both Chang Lee and Grace Holloway were brought back to life by the TARDIS. The Doctor warned him not to be in San Francisco at Christmas 2,000 and gave him two bags of gold dust to make a new start to his life with.
