Buenos Aires, 2001. When Vilma passes away, few friends and relatives care to attend her funeral. This conspicuous absence sparks the curiosity of her 19-year-old granddaughter, Rocio, who moves into the house her grandmother has left her. In this home haunted by memories, she delves into Vilma's life and uncovers a family history shrouded in tragedy.

Moving seamlessly between Italy at the beginning of the 20th century and Argentina at the beginning of the 21st century, Mothballs draws a poetic comparison between the lives of grandmother and granddaughter. Both women are strong-willed and ambitious, eager to forge their own way, but face pressure from family and society to conform to the paths set for them. At a crossroads in her own life, knowing well the isolation her grandmother felt, Rocio seeks to break free from the chain of history. Mothballs chronicles fraught family dynamics with rare nuance and sensitivity, sprinkling in moments of tenderness, vulnerability, and whimsy amidst the pain, a showcase of tour de force cartooning that marks Sole Otero as a major talent in the global comics scene.
