Warsaw, 1942. Sixteen-year old Mira smuggles food into the Warsaw Ghetto to keep herself and her family alive. When she discovers that the entire Ghetto is to be "liquidated"—killed or "resettled" to concentration camps—she desperately tries to find a way to save her family. She meets a group of young people who are planning the unthinkable: an uprising against the occupying forces. Mira joins the resistance fighters who, with minimal supplies and weapons, end up holding out for twenty-eight days, longer than anyone had thought possible.
During this time, Mira has to decide where her heart belongs. To Amos, who will take as many Nazis as he can with him into the grave? Or to Daniel, who wants to help orphans in a shelter?
