The peregrine falcon can spot its prey from 3km away, has the ability to catch another bird in flight and, when diving in what is called a stoop, can move faster than a Ferrari.

This film, narrated by Peter Capaldi, follows a family of falcons living on a balcony on the 28th floor of a skyscraper in Chicago, and also joins ornithologist Lloyd Buck as he trains a peregrine to do what these birds do best.
