Finally my sister's play has started showcasing on a local theater here in Buenos Aires. It's a nice play, with a interesting layout and some common strong themes, dark, tense, and well-paced. It's called Guárdame como las pupilas de tus ojos, which is a section of a psalm from the old testament I think.

You have to seat on one of four cardinal points, around which the play develops, with I think nine actresses and one actor always on "stage". They never leave the scene, and they keep acting, so each time you see it you should discover new things. Anyway, I've filmed them and made their promo DVD, plus a simple website with stills captured from the video, and the overall graphic design (flyers, cards, etc). Take a look even if you can't go because you're in another continent, for example.
