Caine Monroy's cardboard arcade in his father's East LA auto parts store became an internet sensation after Nirvan Mullick's short film about it went viral, and this follow-up picks up five months later to show what that attention set in motion. It tracks the founding of the Imagination Foundation, built to keep the momentum from the original film going, and the launch of the Global Cardboard Challenge, an event asking kids everywhere to build their own creations out of cardboard and imagination rather than store-bought toys. Footage revisits the flashmob crowd that first surprised Caine at his arcade and follows the idea as it spreads outward into classrooms and neighborhoods far from Los Angeles. Mullick, who directed the original short, narrates the shift from a single viral video to an organized annual event, one that would eventually be marked each fall near the anniversary of that first flashmob. The film is short and plain about its stakes: whether a moment of internet enthusiasm can turn into something kids keep doing every year.
