Dark shadows from a woman's past come back to haunt her in this drama from writer and director Cristina Comencini. Sabina (Giovanna Mezzogiorno) would seem to have a charmed life -- she has a successful career as a voice actress, a loving and supportive relationship with her boyfriend, Franco (Alessio Boni), and a pair of close friends she can confide in, Maria (Angela Finocchiaro) and Emilia (Stefania Rocca). But Sabina's contented existence is shattered when she inadvertently dredges up a long-dormant memory of how during her childhood she was sexually abused by her father. Confused and ashamed, Sabina finds it impossible to talk about her memories with Franco and her friends, but the terrible images refuse to go away. Seeking closure, Sabina travels to the United States to talk to the one person who may have a true insight to her problems, her brother, Daniele (Luigi Lo Cascio). Originally released in Italy as La Bestia nel Cuore, Don't Tell premiered at the 2005 Venice Film Festival.
