Twelve-year-old Simone feels painfully disconnected from the world after witnessing the brutal death of her mother. Simone, a solitary multimedia artist in her twenties, is struggling to control her crushing panic attacks and keep her day job in an underground parking lot. And Simone, a sixty-year-old physicist, is giving a conference on the nature of time. The three Simones' lives are intertwined in a labyrinthine meta-world where timeframes overlap, characters multiply, and storylines repeat and expand. But, for all its shuttling forward and back through time, ENDORPHINE remains grounded in the Simones' inner lives — it's an artistic examination of scientific phenomena that also poignantly explores how people deal with trauma.
