The discovery of a worn pink wrestling mask prompts Nana Lupita, a Wisconsin grandmother, to share her tale about growing up in 1960s Texas. As her tale unfolds, Lupita's life as a teen tomboy comes alive—bike riding with her friends Leopold and Liesl, working at her father's flower stand and lucha libre. When a World Championship match is announced, Lupita anticipates seeing it until she discovers her ailing father is one of the wrestlers. With the help of a magical mask maker, Lupita secretly trains to take her father's place. She soon finds it difficult keeping her secret from her friends and, most importantly, her father.
