The relationship between the two brothers is tested when Rafael meets Helena, Lucho´s girlfriend, a beautiful and charismatic community leader. From that moment on, everything changes. For him, because he can´t get her out of his mind; for Liliana, his wife who he has always adored; and for Lucho, his older brother
