Four months after giving birth, two different women find out that their babies have been switched after birth. To adjust to their new lives, they make a special decision: they will form a family together. On the one hand, there is Ana Servin, a perfectionist who lives a structured life with her husband Juan Carlos. Mariana Herrera is the only daughter of a single mother and grew up with little structure. Her dream is to develop an app to track the baby's physical, emotional and spiritual development to help mothers.
