Johanna Pasquali is a young woman who dreams to be part of the elite national security force RAID. Her father is Interior Minister Jacques Pasquali, who pulls strings to get her in as a trainee with the condition that his involvement remains secret. He secretly plans to make his daughter disillusioned with RAID and no longer want to be part of it. Johanna and the other trainees are the responsibility of Eugène Froissard, whose wife has left him for his brother and is regarded as a jinx by his colleagues. Froissard is furious at the idea of a woman being part of RAID, and intends to find any excuse to make Johanna leave.
