1940年，波蘭冠軍拳王泰迪參與華沙圍城保衛戰的武裝部隊，華沙被破，他在逃亡法國途中被捕，成為第一批被送往奧斯威辛集中營的戰80s。集中營里朝不保夕，納粹士兵視為游戲的地下拳擊賽，成為泰迪為生存而拼搏的重要戰爭。然而，一次次激勵人心的勝利，卻讓納粹長官警覺到囚犯的反抗意識，轉而強化管制，眼見沖突逐漸升溫，獲勝已然成為集中營里殘酷的生存之路。

本片根據波蘭著名同名小說改編，講述了二戰期間，華沙被納粹德國軍隊占領，波蘭童子軍的年輕人們與德國占領者進行英勇斗爭的故潦草網。　　Based on a well-known Polish novel with the same title the movie re-tells a true life story of a group of scouts called ''Szare Szeregi'' (Gray Ranks) during the Nazi occupation of Warsaw and the liberation of one of its members (imprisoned and tortured by the Germans) through a maverick military action in board daylight right under the enemy's nose known ''Action at the Arsenal'' which was the biggest single feat of the sort undertaken by a youth resistance organisation in all of occupied Europe during WWII.
