There's Love, There's Not(1968)

Everything happens during the course of a day. A toddler looks for his lost toy, some people look for their happiness, circling around in some kind of a lost kaleidoscope; they love and hate, suffer and enjoy, being that honest or fake, joyful or saddening. In the end, the boy finds his kaleidoscope, but the question remains if grownups have found their dreams, or at least their traces.
