Now faced with a tight production window with only a vague story idea and dire consequences for failure, Buster and his friends must all stretch their talents put on a show against all odds. In that struggle, the gang's challenges seem insurmountable, but each of them finds new inspirations and friends where they least expect them to pursue an artistic dream worthy of them.
