With this simultaneously harrowing and lyrical debut feature, Jan Nemec established himself as the most uncompromising visionary among the radical filmmakers who made up the Czechoslovak New Wave. Adapted from a novel by Arno₍t Lustig, closely tracks two boys who escape from a concentration-camp transport and flee into the surrounding woods, a hostile terrain where the brute realities of survival coexist with dreams, memories, and fragments of visual poetry.
