莉莉丝找到了一份新工作！为了支付大学学费，她晚上要看守一个富人（雷蒙多饰）的公寓，以防被盗窃或类似事件发生。她认为那个地方没有什么真正值钱的东西，但她需要钱，因此她接受了这份工作，尽管雷蒙多对着装有严格的要求：正式礼服（白衬衫和黑裙子）、长袜和高跟鞋。莉莉丝觉得高跟鞋和长袜特别不方便，所以，只要她一个人在公寓里，她就会脱掉它们，这样会更舒服。
过了一会儿，有人敲门，假装是雷蒙多的朋友。莉莉丝犹豫了一会儿，打开了门，一个蒙面男子闯了进来，用手堵住了女孩的嘴，问房间里有没有绳子。
在下一个场景中，莉莉丝被彻底绑住了，坐在沙发上，包括大脚趾（她受了很多苦）。她告诉那个男人，在她看来，没有什么有趣的东西可以偷，并恳求他离开，但那个男人用几条胶带堵住了她的嘴，然后让她一个人呆着，而他则搜查了这个地方。经过一番徒劳的挣扎后，莉莉丝试图打电话报警，她用放在一张小桌子上的旧电话，用被绑住的大脚趾操作电话，但她的企图被窃贼挫败了，窃贼用手堵住了她的嘴，并告诉警察这是一个恶作剧电话。
莉莉丝的尝试受到了惩罚，窃贼换了口塞（塞满的劈开物）并把她绑在床上，让她更加安静和安全。然后，这个足智多谋的女孩被留在卧室里挣扎，而那个男人继续洗劫。过了一会儿，窃贼带着他的赃物回来了，一件珍贵的文物。离开之前，他在劈开物上套了一个 OTM 口塞，以便让莉莉丝更加安静。
即使被牢牢地绑住，这位勇敢的女孩也没有放弃，经过多次尝试，她成功解开了捆绑绳。这样她就可以爬到客厅，她之前脱下的高跟鞋就放在地板上。她试图把鞋带穿回去，以免被雷蒙多发现光着脚，但她的努力被脚趾绑住的绳子挫败了，这让她没有机会穿上它们。莉莉丝决定再次用她的大脚趾打电话求救。
过了一会儿，雷蒙多出现了，但他没有解开这个可怜的女孩。他首先检查了发生了什么，告诉莉莉丝被盗的文物是假的，因为他是在测试她作为警卫的表现。然后他责骂她脱掉了袜子和鞋子，因此她被解雇了。
最后，他打电话报警，报告了入室盗窃的情况，并告诉警察在他们到达之前他不会碰任何东西，包括被绑住并堵住嘴的可怜的莉莉丝。Lilith has got a new job! In order to pay the college bills, she keeps watch over the apartment of a rich man (Raimondo) during the night hours, in order to prevent burglaries or the like. She believes that there isn't anything really valuable in that place, but she needs the money, hence she accepted despite the severe dress code imposed by Raimondo: formal dress (white shirt and black skirt), stockings and high heels. Lilith finds the heels and stockings particularly inconvenient, so, as long as she's all alone in the apartment, she removes them to stay more comfortable.
After a while someone knocks the door, pretending to be a friend of Raimondo. Lilith, after some hesitation, opens the door and a masked man breaks in, handgagging the girl and asking if there are ropes in the place.
In the next scene Lilith is thoroughly bound, sitting on the sofa, big toes included (she suffers it a lot). She tells the man that, in her own opinion, there's nothing interestiing to steal and begs him to go away, but the man gags her with some strips of duct tape and leaves her alone, while he searches the place. After some useless strugglings, Lilith tries to call the police, using an old telephone lying on a small table and operating it with her bound big toes, but her attempt is thwarted by the burglar, that handgags her and tells the cop that it was a prank call.
Lilith's try is punished with a change of gag (a stuffed cleave) and a hogtie on the bed, to keep her even more still and secure. The resourceful girl is then left struggling in the bedroom, while the man keeps on ransacking. After a while, the burglar comes back with his loot, a precious artifact. Before leaving, he applies an OTM gag over the cleave, in order to keep Lilith even more quiet.
Even if securely immobilized, the valiant girl doesn't give up and, after many tries, succeeds in undoing the hogtie knot. This allows her to crawl her way to the living room, where her previously removed heels lay on the floor. She tries to put them back on, in order not to be found barefoot by Raimondo, but her efforts are frustrated by the toe-tie, that prevents any chances to wear them. Lilith decides then to use again the phone with her big toes to call for help.
After a while Raimondo shows up, but he doesn't untie the poor girl. He first checks what happened, telling Lilith that the stolen artifact was a fake, because he was testing her as a guard. He then scolds her for having removed her stockings and shoes, hence she's fired.
Finally, he calls the police and reports the housebreaking, telling the cops that he's not going to touch anything until they arrive, including the poor bound and gagged Lilith.
