Jutta Schmidt is shocked when several members of the Council of National Defense show up on her family's doorstep. Sure, the Schmidts once lived in the Amana Colonies, but that was years ago. She's even more surprised when the council demands that she travel to Amana and report back on any un-American activities. Not daring to disobey the government agents, Jutta takes a job at the South Amana hotel, befriends the daughter of the owners, and begins to eavesdrop every chance she gets.
