As a result of their peculiar practices and growing up the only Black children in a small town in Wales in the ’70s, both girls suffer ridicule from their peers, and later, speculation and scrutiny from society. Growing up, June and Jennifer withdrew into each other to create a colorful world and language just for them, but soon come to find out that society doesn’t often take kindly to those who seek to live outside the rigid margins.

Through both dreamy imagery typical of Smoczynska’s filmography and stop-motion animation,Andrea Seigel’s screenplay explores the twins' writings and institutionalization as reported by Wallace. The sisters developed a system through which they expressed their feelings and understanding of the world around them, one that allowed them to create lyrical poetry. When perceived to be unfit mentally, due their lack of communication with others, June and Jennifer are shipped off to an institution that proves to be more harmful than good. The girls descend into anti-social behaviors that bring down more disdain by those who cannot understand them.
