A group of stable hands is given a race horse when its owner retires from the business. (The group is played by the "Original Sing Band," which uses their mouths to sound like musical instruments.) They raise money to run the horse in the Hollywood Derby at Santa Anita race track. Many Hollywood personalities attend the event.
阳光明媚的一天，大力水手卜派（杰克·梅瑟 Jack Mercer 配音）和奥莉弗（梅伊·奎斯托尔 Mae Questel 配音）约会。他唱着快乐的歌曲，心情愉悦。走着走着，卜派发现一家旱冰场。于是他有了好主意，决定和女友在旱冰场约会。不过奥莉弗对此有些抵触，因为她不会滑旱冰，更怕摔倒受伤。卜派信心满满，保证会手把手教女友滑冰。正在这时，一名小女孩滑着旱冰路过二人，结果一不小心摔倒在地哇哇大哭，这个遭遇更令奥莉弗多了几分恐惧。不由分说，卜派将女友拉到窗口购买门票，选择合脚的旱冰鞋，然而两人走入溜冰场。
奥莉弗笨手笨脚，随时都会滑倒，卜派耐心教授，却无法避免意外的发生……
