David Walker disappeared in the summer of 1969 and was assumed dead. Imagine going to work one day, then waking up in 2019 without knowledge he had gone to sleep for fifty years in suspended animation. Would he be able to live successfully in the life he now faced, being the world's first cryonaut, and with a son who he last saw as a three-year-old, who was now an older man? It was difficult trying to cope with the latest technology, and he was sad that he had missed the birthdays, anniversaries, and deaths of those he loved - in particular his wife, Blossom. David continued to work with the Suspended Animation Program, with little knowledge that his pioneering work would be used to save his son from a cruel, debilitating disease. But, a sinister plan was afoot when his son was captured, facing certain death.
