Two good friends named Becky and Hunter are addicted to adrenaline and embark on the wildest adventures to get it. Becky suffers from the loss of her husband when he falls while climbing. 51 weeks after her husband’s death, Becky has become a depressed alcoholic who has distanced herself from her father because he believes her husband was not as good a man as she thinks he is. Wanting to help Becky, Hunter invites her to climb a 2,000-foot-tall desert TV tower to dispose of Dan’s ashes, but the ladder they climbed breaks and the two are stranded at high altitude.
