A female bomb disposal expert gets trapped in her car with two children and an anti-tank mine planted under the vehicle. She and her boyfriend will only have one chance to defuse the bomb and 30 minutes to do so.

In a Parisian parking lot Sonia finds herself trapped in her car with her son and the daughter of her boyfriend Fred, who has been left outside, powerless to deal with the situation: an anti-tank mine has been set under the car. Sonia is a bomb-disposal expert, who works for a NGO with Fred. She just got back from a mission in Ukraine and, while she's used to face dangerous situations, with the children's lives on the line the stakes have never been higher. Along with colleagues Igor and Camille, who came to the rescue, Sonia and Fred have 30 minutes to defuse the bomb and work out who could be the mastermind behind this. Will they stand united until the end or will the family implode under pressure?
