Synopsis:
Dick Grayson is struck in the head when he saves a falling woman. The blow causes partial amnesia. Dick forgets everything that happened since his parents died including his adventures as Robin.

Bruce Wayne decides not to tell Dick that he is Robin. Instead, he trains Dick as Robin's stand-in in hopes that Dick's memory will return. When Batman's efforts prove unsuccessful, he tries another idea. Batman falls off a building which causes Dick to remember his parents fall and that of the woman he saved. The shock restores Dick's memory. Batman is saved by a safety net that he put in place prior to the fall.
