Albert Einstein spends his final hours in a Princeton hospital bed still working, asking only for his glasses, a notepad, and his latest set of equations. The film follows that last project, decades spent chasing a unified field theory that could tie gravity and electromagnetism into one set of laws, a search he sometimes described as trying to read the mind of God. Physicists and historians interviewed here walk through why the problem consumed him even as his health failed, and what made it different from the work that had already made him famous. Personal recollections from people who knew him fill out the picture of a man who kept a pencil moving until there was nothing left to write with. The film treats the unfinished equations less as failure than as the last stretch of a career spent refusing to stop asking questions about how the universe fits together.
