Once apart, they each begin to feel empty without the other, and realized they need to make an effort to understand each other.
The lives of six girls belong to different worlds although connected to each other through a doll called Molly, whose existence dates back to 1976, when she appeared among the rubble of the great fire of the San Carlos orphanage, in northern Spain.
