Three twelve year old kids named Blue, Green, and Tangerine gather around a sandbox in a studio apartment. Each is carefully building their own sand city. As their cities grow, the boundaries between their territories become unclear, leading to playful but growing tensions. When a prized toy goes missing, suspicion and distrust arise, and the children arm their cities with toy soldiers and begin fighting for control. The sandbox turns into a miniature war zone, with shifting alliances and ever changing borders in a cycle of conflict. Meanwhile, a lone plastic figure called Plastic Man who lives in the city, watches the chaos with concern for his family’s safety.
