Samantha Who?

After a hit-and-run accident left Samantha Newly (Christina Applegate) in an eight-day coma, she awoke with retrograde amnesia, which allowed her to fully function in the world but leaves her with no personal memories of her past. As she began her quest to rediscover herself, she learned that she had been a horrible person. Vain, selfish and potentially surrounded by far more enemies than friends, she made a conscious decision to improve herself moving forward with the help of her eclectic friends and family.
