Seven contestants climb into an fMRI machine at Stanford one at a time and get five minutes to neurochemically love someone as hard as they can, while researchers watch their brain activity on a screen. Director Brent Hoff frames the setup as a real contest, complete with a winner, but the machinery underneath is genuine neuroscience: the scanner tracks blood flow to regions associated with attachment and reward while each person tries to summon the feeling on command. Contestants take wildly different approaches, some replaying specific memories, others focusing on a photograph or a person in the room, and the film lets the differences speak for themselves rather than ranking them. Scientists comment on what the scans can and cannot tell you, and the film is upfront that intensity on an image is not the same thing as love itself. The contest format gives the science a hook, but the more interesting material is watching people try to perform an involuntary emotion under lab conditions and clock, in real time, whether it works.
