It's been a month since Lucy started living with Thomas and his mom. Everyday she must clean the kitchen and bathrooms. Lucy goes to the hospital every chance she gets, but nothing has changed. Until that one day. One day, the girls do wake up. They know they were in an accident, but they don't remember Lucy. Lucy must stay with the girls every weekend to see if they will remember her. Since the girls don't remember Lucy, she refused to talk. Her heart is chained and her sisters are the only ones with a key. Will the girls realize they are better together with Lucy?
