Two sisters try to make Superman apathetic with red kryptonite by shooting its red beam at him so that they could steal $20 million. Because he is hugging Lois, trying to protect her from the beam, his powers are transferred to her. The Kents help create a secret identity to the powerful Lois so she could help people without exposing her real self. This experience opens Lois' eyes to the struggles Clark has been going through all his life trying to save as many people he could and dealing with the ones he wasn't fast enough or strong enough to save.
