Back to 15 Follows Anita's self-discovery and maturity journey. At 15, the young played by Maisa, had a great expectation of adult life: leave the tiny town Imperatriz, travel to many places and get to know a lot of people. But at 30, her life is nothing like that. With few friends, living in a renovated apartment and with no signal of love, Anita returned to her birth town for her sister Luiza's wedding.
