Longtime single friends, Ben and Alice, agree to be each other's respective plus one at every wedding they're invited to, during a busy summer of wedding fever.

In 1908, amateur naturalist and pioneering filmmaker Percy Smith stunned early cinema goers with his footage of the juggling fly. Hailed as the father of Natural History film, Smith was a hugely influential visual pioneer, inventing many techniques that are still used today. Being both a genius and an eccentric, we follow his life from his earliest films, to the collapse of his house from his mould experiment to his ultimate suicide. We also meet Natural History icon Sir David Attenborough, who was so amazed by Smith’s films in the 1930s that they inspired him to get into natural history.
