Things aren’t looking good for Helen Dorn: A dramatic chase results in two dead – and leaves her with a gunshot wound to the chest. Though Helen survives emergency surgery, not even the gruff love of her father Richard is enough to save her from the physical and mental repercussions. The consequences are bitter. Just as the decision is made to put Helen on desk duty, she meets Felix, a young federal agent, who asks for her help on a very special case. A message in a bottle sent from Prague contains a barely-legible cry for help from a kidnapped man long-since considered dead. Germen entrepreneur Paul Westerberg had been kidnapped in Prague in 2014, but all trails leading to the kidnappers had gone cold. This recently discovered message turns the whole case on its head; it means the kidnapping was never about ransom money, but revenge.
