德文和莱妮是一对表姐妹，她们正沉浸在祖父去世的悲痛之中，前往律师凯蒂·奎因的办公室。走进昏暗的房间，她们感到一阵寒意袭上脊背。凯蒂神情凝重地迎接她们，并示意她们坐下。她开始宣读祖父的遗嘱，遗嘱中提到，如果她们能在一个小时内挣脱束缚，其中一人将继承祖父的全部遗产。

莱妮和德文被粗绳紧紧捆绑着。她们挣扎着想要挣脱，却无济于事。恐慌袭来，她们拼命地试图解开对方的束缚，但嘴里的布条堵住了她们的声音。她们一起用力拉扯绳索，渴望继承遗产。

几次尝试失败后，她们终于设法松开了嘴里的布条，可以更有效地交流了。她们重拾决心，齐心协力地解开了捆绑她们的绳索。莱妮感觉到德文的手指笨拙地解着她身上的绳结，很快她就挣脱了束缚。她迅速解开了德文的绳子，两人都发出了胜利的欢呼。

她们喘着气，莱妮争辩说自己逃脱得更快，所以应该继承遗产。但德文指出，正是她的帮助最终才让她们重获自由。最后，她们发现了祖父的一些秘密，故事也随之发生了转折。Devyn and Laney, two cousins mourning their granddad's passing, make their way to the office of lawyer Kitty Quinn. As they enter the dimly-lit room, a chill runs down their spines. Kitty greets them with a somber expression and gestures for them to take a seat. She begins to read their grandfather's will, revealing that one of them will inherit his entire fortune if they can escape the ropes binding them within the next hour.
Laney and Devyn are tied up tightly with thick, coarse ropes. They struggle against the constraints but find no give. As panic sets in, they frantically try to free each other, their voices muffled by the cloth gags in their mouths. Together, they strain and tug at the ropes, desperate to claim their inheritance.
After several failed attempts, they manage to loosen their gags and communicate more effectively. With renewed determination, they work together to loosen the ropes binding them. Laney feels Devyn's fingers fumble at her knots and soon she is able to break free. She quickly unties Devyn and both of them let out triumphant cries.
As they catch their breaths, Laney argues that she escaped faster and should therefore claim the inheritance. But Devyn points out that it was her help that ultimately led to their freedom. In the end, they find out some of their grandfathers secrets and the story takes a twist.
