There are 3 sisters with their different characters. There's Lindsey who has 3 children. We can say she has a happy family. And there's Jenny, whose a very bold woman, very proud to be a mom. And of course, Helen, she has a good job, she's a single woman who has everything she wants.
Life is perfect for them, until one day when Lindsey and her husband died. And they chose Helen over Jenny to be their children's guardian angel.
Overall, the story is about how Helen rediscovered herself while having her sister's children.
