Playdate is based on American/Norwegian author Dahl’s (no relation to Roald Dahl) fourth novel.
In Playdate, a seemingly ordinary decision turns the world of Elisa, mum to two young kids, upside down. When Elisa’s nine-year-old daughter asks to go on an overnight playdate with her new best friend, Elisa agrees. But when she says goodnight to her daughter, she has no idea that she is about to be thrust into every parent’s worst nightmare, and when Elisa goes to pick her up, she discovers that the beautiful house was a holiday rental, while her daughter has disappeared. What follows is a manhunt across Europe, while Elisa and husband Fred find themselves the object of police scrutiny.
