Val turns to religion in the hopes of getting her parents back and Lucia denounces that same religion, believing it is only doing harm to her younger sister. Meanwhile, Emilio tries to do right by his father by dismissing Oscar of certain duties, which only offends Oscar and leaves Emilio to run the restaurant on his own.
The Acosta siblings, Emilio, Lucia, Beto, Valentina and baby Rafa struggle to stay together in the wake of their parents' deportation. Forced to shoulder professional and parenting responsibilities for which they are ill-equipped, the siblings must grow up quickly.
