Becky has always been an extreme person, but after the death of her husband, she decided to stop chasing adrenaline. However, she needs to make one more, the last ascent – together with her friend, she climbs to the top of a remote, abandoned 2,000 feet high radio tower to scatter the ashes of her late husband. By chance, this place has become an insidious trap of cold and death. Now they have to fight the elements, lack of supplies, and vertigo-inducing heights on the way to salvation.
