贾姬（苏珊·萨兰登 Susan Sarandon饰）是路克（艾德·哈里斯 Ed Harris饰）的前任妻子。她为他生下一对儿女，精心操持家务，却终因性格不合而宣告婚姻失败。离婚三年来，儿女一直由贾姬和路克轮番照料，生活倒也波澜不惊，直到女摄影师伊莎贝尔（朱莉娅·罗伯茨 Julia Roberts饰）和路克堕入情网，矛盾开始繁衍激化。
　　伊莎贝尔搬到路克家来，一心一意要做一个合格的继母。即使她没有多少持家经验，但还是设法和孩子们快乐相处，让他们接受自己。事与愿违，在孩子的心中，谁也无法替代生母贾姬的地位。而贾姬的心情更是复杂。她已经身患癌症，当然盼望有个好继母照顾孩子。可是，妒嫉心却让她不愿看到伊莎贝尔和孩子们情如骨肉。病症一天天恶化，心理挣扎的贾姬，终于有了令人释怀的决定。

　　Johnny Casar (Mickey Rooney) runs away from a home for wayward boys, tired of being teased about being short and a poor athlete. He soon finds a pair of roller skates and is befriended by Bruno Crystal (Ralph Dumke), who allows him to wash dishes at his café, while a priest who runs the home, Father O'Hara (Pat O'Brien), secretly keeps an eye on him.
　　A traveling roller-skating team takes an interest in Johnny after he shows some aptitude. He clashes with Mack Miller (Glen Corbett), a cocky champion, and falls for Mary Reeves (Beverly Tyler), another top skater. Johnny ends up featured in grudge matches against Miller, where they take turns one-upping one another.
　　As his fame grows, Johnny becomes every bit as arrogant as Miller and more. Life takes a bad turn when he is diagnosed with polio. A long period of physical therapy follows, until a wheelchair-bound Johnny tries to get his life back on track.
