Cecelia Ahern's sitcom hits our screens tonight. Hasn't she just been the best ambassador for Irish writing EVER?! Samantha 'Sam' Newly (portrayed by the sublime Christina Applegate) is a corporate executive and hit-and-run victim who awakens after being in a coma for eight days, only to find she has (you've guessed it) amnesia. With no memories of the past, she must rediscover everything about her life and herself by looking for clues from her past. Sam discovers that she wasn't a very nice person to most people and she is determined to change that. She also discovers that she cheated on her boyfriend Todd (played by Barry Watson) with a married man. She even learns that her "accident" was no accident at all, but a failed attempt at someone trying to kill her, but who? Slowly but surely little parts of her start to emerge to the delight of some and to the shock of others.
