After the Crash

On a fateful night in December 1980, a plane crash near the Swiss Alps leaves all but one of the 169 passengers dead, with a three-month-old girl as the sole survivor, sparking a mystery over her true identity. With two infants on board, the families of Lyse-Rose and Emilie vie for the child, leading to a stark contrast between the struggling Vitrals and the wealthy, powerful de Carvilles. Eighteen years later, a detective, Crédule Grand-Duc, uncovers a hidden secret while a university student named Lylie entrusts a crucial notebook to her boyfriend, Marc, just before disappearing. As Marc races to find her, he discovers that he is not alone in his search.
