Daniel and Ana 2009 Mexican thriller s.x drama

Daniel and Ana live with their wealthy parents in Mexico City. He has a girlfriend, Mariana, while she is soon to be married to Rafa, who wants to take a job in Spain. The two are kidnapped at gunpoint and, under threat of being raped and killed, are filmed stripping and having sex. Though returned home unharmed, their lives are shattered: they cannot talk to each other or to anybody else.

In time Ana proves more resilient, consulting a psychiatrist and reconciling with Rafa. But Daniel's emotional state remains in turmoil, because he was not wholly repulsed by sex with the attractive older sister he has always loved, even though theirs was a situation of coerced rape and not love. He buys a dagger to take to Ana's wedding, but is unsure who to kill.
