The Attack opens like a love story, with a woman telling her husband that every time they separate, "a part of me dies." In light of what happens next, those words take on another, more ominous meaning.
Set in Tel Aviv and the West Bank town of Nablus, the taut but messily honest tale is the story of Amin (Ali Suliman), a prominent Israeli surgeon of secular Palestinian background. He wakes up one morning to discover that his beautiful wife Siham (Reymond Amsalem) has become a suicide bomber, responsible for blowing herself up in a restaurant, along with 17 other victims, including 11 children celebrating a birthday. It's 3 a.m. when Amin gets the call to identify his wife's body, or what's left of it. The grisly fact that there's not much left of Siham from the rib cage down is pretty much all the incriminating evidence that the police need.
That doesn't stop Amin, who is also initially cast under suspicion, from believing there must be some mistake. As it becomes increasingly obvious that the mistake was his - in overlooking whatever clues there might have been to Siham's secret life as a Palestinian terrorist - he sets out to answer a difficult question: "How do you make a fundamentalist monster out of a woman who wouldn't hurt a fly?"
The search takes him to Nazareth, where his wife was from, and then to Nablus, where she spent the last night of her life. What he ends up finding along the way are only more questions.
