Gerardo Escobar
Paulina's husband, he is a lawyer about forty-five years of age. Gerardo has recently been appointed by the president to a commission that will examine human rights abuses during the military dictatorship. Gerardo has a high ideal of justice which he invokes in an attempt to persuade his wife to release Miranda. Paulina is ethically motivated, too, but she stresses repeatedly that corruption in the country's legal system leaves considerable doubt that the military's abuses will be properly rectified. Gerardo maintains his faith in the government's ability to do the best it can do under the circumstances, while Paulina feels pushed to take matters into her own hands. Undoubtedly, her more personal resolve is the product of her abduction and torment, which Gerardo seems to find almost unfathomable on a personal level, despite the nature of his work.

Gerardo has always had great difficulty discussing Paulina's experience, a guilt that is compounded by the fact that when Paulina went to him following her release, she discovered that he had been having an affair in her absence. Gerardo's suggestion that Paulina make a tape recording may be a way of addressing his problem, putting words to something he has not wanted to face.

Doctor Roberto Miranda
A doctor, around fifty years old. Roberto—Doctor Miranda—remains indignant at Paulina's accusations. He repeatedly reminds Gerardo of his place on the human rights commission and that it is his duty in that capacity to command his wife to release Miranda. The doctor denies having had any role in torturing military abductees and offers a confession that he claims to have fabricated in the hopes that Paulina will release him unharmed Miranda, however, corrects details in the narrative of Paulina's experience which she recorded for Gerardo; this is enough proof for Paulina that her prisoner is the doctor who raped and tortured her. Miranda does not succeed in convincing her to the contrary but without having to make a direct and true confession he does somehow convince Paulina to spare his life with his plea, "Oh Paulina—isn't it time we stopped?''

Miranda is a mysterious character who Dorfman never fully reveals to the audience. While there is considerable evidence presented that seems to incriminate the doctor, the possibility remains that it is merely coincidence that he fits the profile of Paulina's tormentor. His guilt appears to be further cemented by his decision not to report his kidnapping to the authorities, yet his silence may be attributed to a fear that Gerardo may use his position on the commission to discredit Miranda. Dorfman does not offer explanations for any of these situations. Miranda's fate at the play's conclusion is ambiguous: he may be a guilty man tormented by the atrocities he committed during wartime, or he may be an innocent man terrified by the threat of an unbalanced woman.

Paulina Solas
As a young student in the early days of the military dictatorship that ruled her country (the specific location is never given), Paulina worked with Gerardo helping people seek asylum in embassies and smuggling them out of the country. Paulina's activism, and her medical studies, were cut short, however, when she was arrested by the government. She was tortured and raped repeatedly before finally being released. This devastating experience which so altered her life continues to affect her seventeen years later, when the action of the play occurs.

Paulina has suppressed the worst details of her incarceration. Her paranoia has prevented her from sharing this information with Gerardo or her mother—for fear that the knowledge might place them in danger. While her country has replaced the dictatorship with a free, elected government, she suspects that many in power are from the military and only pretending to be democratic and fair-minded. She lives with acute fear, as can be seen from her defensive actions when Roberto Miranda's unfamiliar car first pulls up to the house. Since her ordeal, Paulina has also stifled a great deal of anger, which surfaces with the opportunity to exact revenge on the man she believes was her primary tormentor. Sure of herself after "trying" Miranda, Paulina appears set to kill the doctor but ultimately chooses to be merciful. This action seems to suggest that she ultimately rejects the idea of an eye for an eye. Yet her humane gesture comes at a price to her piece of mind. The tense final image of the play suggests that Paulina may never be able to achieve a satisfying resolution to her lingering pain.
