The action of this stems out of Philadelphia where Genl. Stirling has sent dashing Capt. Jonathan Kimball to get military and psychological information. Jonathan poses as a servant in the home of beautiful Elizabeth Ladd and the importance of his mission grows as Washington senses British peace feelers granting all but outright independence. Without losing its telling quality, story action shifts to Valley Forge and with its tense descriptions turns into good cloak and dagger history.
