Over the course of 60 years, two married entomologists traveled to more than 67 countries and quietly amassed the world’s largest private collection of insects, with more than 1 million specimens. But as they grapple with Parkinson’s and their twilight years, these two soulmates — married for 55 years — decide to give the collection away. This humorous and poignant documentary explores the love of nature — and the nature of love — and what it means to devote oneself completely to both.
