夜幕降临，公司里的人都已下班回家，唯独麦迪逊（Madison）决定留下来加班。正当她在键盘上敲打时，隐约听到隔壁办公室传来声响，便起身查看，不料却遭闯入者突袭。转瞬间，她的嘴已被封箱胶带封住，手腕和脚踝也被紧紧勒住——那是坚固得难以挣脱的束线带。麦迪逊费力地从地板上挣扎着爬回办公椅，但由于无法挣脱束线带的束缚，她已无计可施，只能等待有人发现并解救她。It is evening and everyone at the company has gone home, apart from Madison who decided to work late on this occasion. As she types on her keyboard, she thinks she hears a sound in an adjacent office and goes to investigate, only to be jumped by an intruder. She quickly finds her mouth gagged with duct tape and her wrists and ankles snared by unforgiving zip ties. Madison manages to struggle from the floor up on to her office chair, but since she can't break free of the zip ties, there is little more she can do except wait for someone to find her and let her go.
