During World War I, a novelist declared dead is recruited by British intelligence and sent to Switzerland under a new identity to assassinate a German spy. Teamed with a fellow agent posing as his wife and an eccentric assassin known as “the General,” the trio close in on their target — until two of them grow ambivalent when their duty to the mission clashes with their consciences.
