The picture has a number of producers, including: Mariela Besuievski, Pablo Bossi, Florencia Enghel, Gerardo Herrero, Vanessa Ragone, Walter Salles, and Ariel Saúl.

The film is based on the real political events that took place in Argentina after Jorge Rafael Videla's reactionary military junta assumed power on March 24, 1976.

During the junta's rule: the parliament was suspended, unions, political parties and provincial governments were banned, and in what became known as the Dirty War between 9,000 and 30,000 people deemed left-wing "subversives" disappeared from society.

The complex plot doesn't fully exploit the possibilities for suspense, but first-class perfs, great atmospherics and an upbeat message combine to make the pic work better as a sibling drama than as a thriller.

"[6] Film critic Ed Gonzalez wrote, "Solomonoff doesn't strike very interesting contrasts between past and present, but her actresses certainly do: Rubio and Bertucelli express how resentment eats away at their characters' sisterhood so richly that the many flashbacks to Argentina, shot uninterestingly in gritty hand-held gestures, seem almost unnecessary.
