A Father's Miracle remakes the South Korean film Miracle in Cell No. 7, changing the protagonists from Asian to Latino, which constitutes a race swap for the main characters.

The film affirms devoted single fatherhood through Héctor's selfless sacrifices for his daughter, embedding themes of familial resilience and compassionate authority within a melodramatic prison narrative. This endorsement of parental endurance and unity drives a traditional framing of family bonds.

Catholic elements like church scenes, a Virgin Mary statue, and references to death as becoming an angel frame the protagonist's innocence and resilience as saintly. The narrative uses these motifs to affirm themes of forgiveness, compassion, and miraculous redemption through familial bonds.
