Kosmos (2015)

It is the near future and research scientist Philip Hoyt's wife is dying, quietly. As she lies in a deep coma, Philip battles to save her life when everyone else is ready to let her go. Using a newly developed technology, he steps across an electronic bridge into her unconscious; into her dreams and memories, probing buried 'psi-complexes' to discover the mystery of her illness, and her families reluctance to help. Yet, through the veil of this mystery, he catches a faint glimmer of life. He holds on for the sake of love, unable to turn away from that distant star we call hope.
