Copenhagen, 1940

When the Germans march into Denmark, Baron Henrik Ahlefeldt exchanges his nobility for anonymity, assuming a new identity so he can secretly row messages for the Danish Resistance across the waters to Sweden. American physicist Dr. Else Jensen refuses to leave Copenhagen and abandon her research--her life's dream--and makes the dangerous decision to print resistance newspapers.

As Else hears rumors of the movement's legendary Havmand--the merman--she also becomes intrigued by the mysterious and silent shipyard worker living in the same boardinghouse. Henrik makes every effort to conceal his noble upbringing, but he is torn between the façade he must maintain and the woman he is beginning to fall in love with.

When the Occupation cracks down on the Danes, these two passionate people will discover if there is more power in speech . . . or in silence.
