Festival de Cannes 2008 Official Selection
Synopsis from the offical site: “One night at a bar, an old friend tells director Ari Folman about a recurring nightmare in which he is chased by 26 vicious dogs. Every night, the same number of beasts. The two men conclude that there’s a connection to their Israeli Army mission in the first Lebanon War of the early eighties. Ari is surprised that he can’t remember a thing anymore about that period of his life.”
