斯特拉走进一间公寓，她独自一人，一切都很安静，她在寻找什么东西……突然，她听到了声音，她转过身，我们看到的只有她那张惊恐的脸……斯特拉现在被许多绳子和一个大 OTM 绑在一个黑暗的房间里。她挣扎着，想挣脱，但绳子太多了。她面前有一面镜子，她看着自己被绑着、堵着嘴，她注意到电话的存在，她走近了，设法用现在赤裸的双脚拨了一个号码。

私家侦探阿尔巴接了电话，她的心被这个电话唤醒了，她回答了，但她只听到呻吟声……突然，电话挂了，斯特拉发现自己被捆绑了。

与此同时，天已经亮了，阿尔巴醒来，发现卧室门下有一张纸条，上面写着一个地址：“过来，是关于晚上给你打电话的人的。”阿尔巴感到困惑，情况变得越来越复杂，她决定立即前往她得到的地址……

与此同时，斯特拉仍然被捆绑着，挣扎得筋疲力尽。最后，阿尔巴赶到，尽快解开了斯特拉，但意外就在眼前……斯特拉解开后，阿尔巴措手不及，遭到了斯特拉的袭击，斯特拉非但没有感谢美丽的阿尔巴，反而用强有力的手堵住了她的嘴。

现在，阿尔巴被紧紧地绑在椅子上，面对着镜子，用巨大的胶带堵住了嘴，女孩根本动弹不得，只能挣扎和呻吟。几分钟后，斯特拉回来了，讽刺地告诉阿尔巴，她想把她放在一个更舒服的位置……Stella enters an apartment, she is alone, everything is silent, she is looking for something... Suddenly she hears a noise, she turns around, and all we can see it’s her scared face... Stella is now tied with many ropes, and a big OTM, in a dark room . She's struggling, trying to free herself but she has too many ropes. There is a mirror in front of her, she looks at herself tied and gagged, she notices the presence of a telephone, she gets closer, and manages to dial a number using only her now bare feet.

Alba, a private investigator, answers and is awakened in her heart by this call, she replies but she only hears moans... Suddenly the call is ended, and Stella finds herself in hogtie.

Meanwhile, it is morning, Alba wakes up and notices that under the door of her bedroom, there is a note with an address written and: "come here, it's about the person who called you during the night". Alba is confused, the situation is getting more and more intricated, she decides to go immediately to the address she was given...

Meanwhile, Stella is still in the hogtie, exhausted from struggling. Finally, Alba arrives and unties Stella as quickly as she can, but the surprise is just around the corner... Once Stella is untied, Alba is taken by surprise and is attacked by Stella, who instead of thanking the beautiful Alba, immobilizes with a strong hand gag.

Now Alba is tied tightly to a chair, facing the mirror, with a huge tape gag, the girl is unable to move at all, and can do nothing but struggle and moan. After several minutes Stella returns, who ironically tells Alba that she wants to put her in an even more comfortable position...
