主角是一只很小很英俊的小猪大侠。为此，大蝈蝈精心制作了机器猪、机器鸡、机器狗等"演员"，但这些机器动物都没有表情，无法以假乱真。于是大蝈蝈到处物色合适的动物演员，配合机器动物表演。当他在电视上看到荧光小猪的表演时，决定要不惜一切代价把荧光小猪弄到手。小猪莫跑跑在完全不知情的状况下，被大蝈蝈带进了这个神秘的摄制组。他看到了一群穿着古代衣服的真动物和机器动物：公鸡皇帝和大臣、猫姐和猫妹、沙皮狗、黑背......残忍的大蝈蝈为了追求电影的真实感，完全不顾惜动物演员的性命，小猪莫跑跑不仅要逃出剧组拯救自己，还要拯救所有无辜的动物们......(The protagonist is a very small but handsome hero – a pig. For this, the big katydid meticulously makes such "performers" as the robotic pig, the robotic chicken and the robotic dog, but these robotic animals fails to mix the false with the genuine because of showing no expressions. Hence, the big katydid looks for appropriate animal performers everywhere to assist the robotic animals in performance. As he sees the performance by the fluorescent small pig from the TV, he decides to get the fluorescent small pig at any price. Before being aware of this condition, the small pig Mo Paopao is conducted into this mysterious camera crew. Mo Paopao finds a group of real animals and robotic animals wearing ancient clothing there: the cock emperor and ministers, the elder cat sister and younger cat sister, the shar pei, the German shepherd dog and so on. For the purpose of pursuing the sense of reality, the cruel katydid completely ignores the lives of animal performers. In this situation, the small pig Mo Paopao needs to not only escape from the camera crew to save himself, but also to save all the innocent animals and so on.)
