Under house arrest, Minerva tries to settle her nerves and adjust to life back at home. She and her sisters can only leave the house with permission from Pena, a SIM guard, and regularly go only to church and to visit their incarcerated husbands. The sisters, as Las Mariposas, have become symbols of the revolution to the Dominican people.
Minerva, at her husband's request, visits some doctors to find out if any of the old revolutionaries is still active. She learns that the movement has been scattered and is waiting for the gringos to overthrow Trujillo, and then they will step in again. The Mirabal sisters receive a warning that Trujillo is annoyed by the favor the "Butterflies" have found with the people. The husbands fear they will soon be killed in prison, and, mysteriously, Manolo and Leandro are transferred to another prison, which can be reached only by driving through dangerous mountain passes.
Although Dede warns that they are vulnerable to a SIM attack, Minerva, Patria, and Mate go to visit their husbands. They arrive safely, but a storm is brewing as they leave, and Manolo begs them to stay the night with friends and go home in the morning. They stop at a restaurant with their driver Rufino, and, unable to get through to the house by phone, decide to travel on home that night (Chapter 12).
