SP讲述了加穗子（高畑充希饰）与初（竹内凉真饰）结婚一年后，一起努力扶持家庭的故事。

女大学生加穗子是一个“被保护过度的典型典范”。凡事都依靠父母解决，无忧无虑地长大，加穗子就像一个“在无菌环境下培养出来的神奇人类”。21岁的她，到了该找工作的年龄，但是别说是兼职了，她甚至从未给自己挑过衣服，或单独乘坐电车，只有别人为自己拍照，从不曾为别人按下过快门。这样的加穗子终于走出抗菌的温室，一头扎进这个满是细菌的世界。然后她才明白“自己跟别人不一样”。然而把女儿当成闺蜜的母亲，和过度依赖女儿的父亲无法维持内心平衡，导致家庭走上分崩离析的道路。此时，加穗子和周围的人发现了沉睡在“温室里的加穗子”心中的真正力量。她经历各种试炼与挣扎，最后成为了“家庭”这一小小王国的女王。

单纯可爱的根本加穗子（高畑充希 饰）虽然已经是一名即将毕业的22岁女大学生，但是她几乎是在父母过度的呵护下长大的。每天早上，她需要母亲（黑木瞳 饰）帮忙叫早、挑选衣服，母女俩几乎融为一体。与此同时，加穗子的父亲（时任三郎 饰）对此感到困扰，可当他看到女儿公主般甜美笑容之时，也不觉内心开始融化，宠溺起女儿来了。然而站在人生十字路口，加上周围人的劝导，加穗子似乎再也不能闷头待在自己的安乐窝中了。她尝试寻找工作，也尝试了解人们的所感所想。 　　对她来说，眼前是一个完全陌生、充满挑战而又极具吸引力的世界……

Nevinost bez zaštite was never released due to the Nazi censors while ironically later during the Yugoslav communist period some accused and condemned it as being pro-Nazi. 　　In 1968 filmmaker Dušan Makavejev found the film and expanded upon it with newsreel footage of Nazi Propaganda and German occupation as well. Other footage includes Aleksić performing his acrobatics and filmed interviews of the surviving cast members. Makavejev tinted some of the black and white scenes in the film and hand colored some details.
