"Irrational Man" examines the limits of human cognition. In a slapstick narrative that appeals to synaesthesia nostalgia, we are guided by a chromatic oscillation that disturbs our cerebral hemispheres in a rhythmic unravelling that breaks the linearity of perception. This oceanic sensoriality, tested by a voice over that confronts the gap between the body and the mind, provokes a strange actualization of our doubts, reflected in the machine-like gestures of the primate in front of us.
