在这部塑料发明家喜剧/动画/短片/家庭片中,平静的一天，唐老鸭（克拉伦斯·纳什 Clarence Nash 配音）正在收听广播。此次的广播是较大家如何用一些废旧材料倒模，做一架塑料飞机。唐老鸭兴致高昂，跃跃欲试，他将身后堆积如山的各种废弃物一股脑扔入硕大的铁锅内，经过一段时间熬制，直到锅里的液体变了颜色，随后倒入事先做好的模子中等待成型。接下来，唐老鸭利用这段时间，用面粉做了齿轮、螺母等小零件，有趣的是这一过程和做面包、蛋糕的方法极其相似。稍后，倒模成功，唐纳德又做了飞行帽，信心百倍地驾驶着他的新飞机试飞。
起初一切顺利，塑料飞机甚至能以很高的速度滑翔俯冲，可当暴风雨临近时，意外终于发生了……
Donald is listening to a radio program that tells how to build an airplane from plastic, in a process much like baking a cake, cookies, and making toast. He takes it out for a test flight, still guided by the radio, and it works wonderfully. Until the radio interviewer asks if there's any problems: yes, it melts when it gets wet. Of course, Donald instantly flies into a rain cloud, and has to battle his plane as it disintegrates.
