松江市，一个东北边陲的小城，一群来自全国各地的农民工为了生存，来到了这里，他们把汗水浸透在这个城市最现代化的高级公寓的建筑工地上。而在旁边的简陋工棚里，上百名民工们围着工长谢老大（马少骅饰）质问发工钱的事，谢老大无奈地告诉大家，答应今天付钱的负责人根本就没有出现。气急败坏的民工们不相信谢老大的话，他们砸开了办公室的门，却发现里面空空如也。血汗工资无情地被非法挪用，民工们养家糊口的工钱被无期限地拖延，为了生计他们被迫集体追讨，可是讨来的却是暴力威胁和致命的恐吓，这群缺乏人文关怀的弱势群体的生命骤然间危在旦夕。大家经过商量后决定大部分人回家秋收，留下王家才（孙松饰）、陆长有（陶泽如饰）、杨志刚（王毅饰）、谢老大和栓子（丁宁饰）五个人作为民工代表去讨要工钱。
