The Death and Life of John F. Donovan takes place in the early 2000s and centers on the tribulations of an American TV star in his late twenties (Harington) and his correspondence with Rupert Turner, a young actor-to-be living with his mother in England. Their lives take dramatic turns when the existence of their pen pal relationship is publicly exposed, eliciting the most ill-founded assumptions, and sending Donovan in a vertical downfall. A decade later, the young actor recollects his relationship with his past idol over the course of an interview.
