“So there’s a theory that we all have a finite number of heartbeats. We all have a billion heartbeats to live. Humans, cats, dogs, rats – all our hearts beat at different speeds but we all have the same amount. A clock with a billion ticks.”

Inspired by the incredible true story of the last greater mouse-eared bat living in Britain, Vespertilio explores the tender romance between introverted bat-enthusiast Alan and Josh, the charming young runaway he meets in an abandoned railway tunnel. As their relationship develops, these two damaged men might fix one another. If only a little. Vespertilio is a story of love, loneliness and bats, an exploration of the difference between merely surviving and truly living.
