Joanna Dark, aka Perfect Dark, is the top agent and pride of the Carrington Institute. Before this, however, she worked as a bounty hunter with her father, Jack Dark. After getting tangled up in an evil plan involving the dataDyne Corporation, she crosses paths with Jonathan Steinberg of the Institute. Daniel Carrington, head of the Institute, is impressed by Joanna's performance in the fight against dataDyne. After foiling their plot, she is recruited into the Institute's ranks.
During her training, she easily unseats Jonathan as top agent, breaking all records previously held by him. Not long afterward, the world is threatened once again by a nefarious dataDyne plot. Joanna is called back into action, and she works to unfurl the conspiracy.
