Manel (a promising, somewhat neurotic Physics graduate) is set to prove to us, in this rom-com/science documentary hybrid, how the laws of physics discovered by Newton, Einstein and the founders of quantum physics can be applied to feelings and relationships, and how come his love a air with Elena (a young, successful model turned into actress) was destined to inevitably fail as determined by those same laws and, specially, by those of a lesser-known discipline: thermodynamics.
