"Tomlinson Hill" is the story of America, as seen through the microcosm of a small Texas town called Marlin. The film takes its name from the former Texas slave plantation that at one time defined this region. We trace this story through the eyes of two descendants - one black - Loreane Tomlinson; and one white - Chris Tomlinson, who independently come back for very different reasons to find their crumbling community still struggling under the weight of 150 years of class separation.

With an interdisciplinary team of climatologists, paleontologists and anthropologists, Broad investigates the hidden history of Earth’s climate as revealed by finds in this spectacularly beautiful “alternate universe.”
