Plot

Sometime in the future, Elizabeth 'Daisy' Rybeck, an irritable, neurotic American teenager, is sent by her father David to the English countryside for the summer to stay with her Aunt Penn and her three cousins: Eddie, Isaac, and Piper. Daisy arrives at Heathrow Airport to tightened security and reports of a bombing in Paris and is greeted by Isaac, who drives her to their farm. Daisy remains abrasive towards her cousins and their neighbour's son, Joe. She learns from her aunt that her late mother Julia, who died in childbirth, also used to stay at the farm frequently. Shortly after her arrival, Aunt Penn flies to Geneva to attend an emergency conference because she is an expert in terrorist extremist groups. Meanwhile, Daisy begins falling in love with her eldest cousin, Eddie.
