"It's a group holiday gone wrong," says actress Jessica Raine about new BBC drama Two Weeks in August. Set on a sun-soaked Greek island, the drama follows a group of university friends reuniting for a long-awaited summer holiday. Now older, the friends are still connected, but marriage, children and mental health struggles have reshaped their relationships. Beneath the cocktails, boat trips and villa life, tensions simmer and emotions rise. Then an illicit kiss threatens to change their lives
