This acclaimed documentary series about the natural world opens Season 40 with "My Garden of a Thousand Bees," which follows filmmaker Martin Dohrn as he embarks on a project driven by lockdown boredom during the coronavirus pandemic. Seeking a distraction, Dohrn sets out to record all the bees he can find on his tiny farm in Bristol, England. During the spring and summer of 2020, Dohrn becomes completely bee-obsessed, going so far as to develop relationships with individual bees, which he can recognize on sight.
