After Dan died in a fall from a cliff, his wife, Becky, who had previously been fond of extreme activities, fell into depression. A year later, the girl still can’t get back to her old self and regularly drowns her sorrows in alcohol when her old battle buddy, Hunter, suddenly appears in her life. She suggests honoring Dan’s memory by climbing the B67 radio mast and scattering his ashes there. The girls head to the tallest structure in the United States, not even imagining what they will have to face at its top.
