The main plot asks questions about the consequences of life choices, of pursuing either career or true love, manoeuvring between now and the past. You play Peter, a Cambridge academic who crashlands in Cold War Antarctica. As he searches for help, his past unwinds before him, revealing how the pressures of power and his own aspirations have led him into this crisis he must somehow escape. A love story between him and fellow academic Clara develops, and Peter learns the weight of all the things he has promised. Like memories from childhood, some promises stay with us forever.
