Toma and Ana meet at university. A love affair begins that is full of hopes and dreams and suffused by the feeling that each needs the other in equal measure. Ana has a complicated family background and suffers from severe panic attacks. Middle-class Toma is as shocked as he is fascinated by the deep well of despair he encounters in his beloved. Toma gives Ana his complete support and takes her to see a string of doctors. At the same time the two begin to isolate themselves from their families and friends. Ana’s weakness appears to make Toma stronger. When she falls pregnant, Ana embarks on a therapy based on analytical psychoanalysis from which she emerges a stronger person. But then Toma’s world begins to topple.
