阿尔芭和斯特拉是一对双胞胎姐妹，都即将大学毕业，但她们是两个截然不同的人……阿尔芭认真学习，斯特拉则比较叛逆，喜欢和朋友去酒吧，而不是看书……正是在其中一次外出时，她遇到了托尼，一个斯特拉曾经接近过的坏男孩……他们按响了门铃，阿尔芭去开门，发现托尼站在她面前，托尼不知道斯特拉有一个双胞胎继姐妹（而且是在晚上在酒吧遇到斯特拉的……），误把阿尔芭当成了斯特拉……阿尔芭不知道斯特拉曾建议托尼用绳子玩色情游戏，然后把男孩扔在门口。然而，托尼是一个不会忘记对他的承诺的坏人，他希望斯特拉的承诺成真。于是他抓住阿尔芭，给她戴上一个很结实的手塞，并用很多绳子把她绑起来。当阿尔芭继续向托尼解释这一切都是误会，他很可能遇到的是她的双胞胎姐妹斯特拉时，托尼显然不相信这位金发女郎，将海绵塞进她的嘴里，并用红色胶带堵住她的嘴......他离开阿尔芭挣扎，而他去厨房休息......经过几分钟的挣扎，阿尔芭试图解开自己但没有成功，斯特拉回到了家......一个大惊喜在等待着她，还有阿尔芭和托尼，他们将要照顾两个不同的双胞胎......对他来说幸运的是（对他们来说不幸的是），托尼是一个充满想象力的男孩，下午很长......他会为这两个漂亮的双胞胎准备什么呢？Alba and Stella are twin sisters, both about to graduate from university, but they are two very different people... Alba is serious and dedicated to studying, Stella is more rebellious, and prefers going out with her friends to the pub to books... It is during one of those outings that she meets Tony, a bad boy that Stella has approached... They ring the doorbell, Alba goes to answer it, and finds Tony in front of her, who, not knowing that Stella has a twin step-sister (and having met Stella at the end of the evening at the pub...), mistakes Alba for Stella... Alba doesn't know that Stella had suggested to Tony that they play erotic games with ropes, and then dumped the boy on the doorstep. Tony, however, a bad guy who doesn't forget the promises made to him, wants Stelle's promises to come true. So he grabs Alba, gives her a strong handgag, and ties her up with lots of ropes. While Alba continues to try to explain to Tony that it's all a misunderstanding and that he has most likely met her twin Stella, Tony, who obviously doesn't believe the blonde, sticks a sponge in her mouth and gags her with pieces of red tape... He leaves Alba struggling while he goes to relax in the kitchen... After several minutes of struggling, in which Alba tries to untie herself without success, Stella returns home... a big surprise awaits her, as well as Alba and Tony, who will have two different twins to manage... Luckily for him (and unfortunately for them), Tony is a boy full of imagination and the afternoon is long... What will he have in store for the two beautiful twins?
