In the second half of the 19th century, Eadweard Muybridge, the father of motion pictures, embarks on an obsessive project to record on film "the motion of life" in all of its abundance. His epic quest is eclipsed only by the depth of his jealousy over his beautiful, young wife Flora. As the project progresses, his paranoia over her fidelity consumes him, until questions arise about his son’s paternity, causing him to erupt.
