Pilar arrives at the Sanctuary, a maternity center surrounded by nature, where she soon experiences strange visions and discovers disturbing coincidences with other women. She suspects that the place hides a dark secret related to pregnancies.

Valle attends an interview at the Sanctuary, where she is told that she needs to improve the gestation incubators for artificial intelligences in simulated bodies of pregnant women, a project that defies the law and seeks to eradicate side effects in the population. Although hesitant, Valle decides to accept the position after consulting with an artificial intelligence that recreates her deceased father.
