Theo Abrams is an ex-Cape Town fireman suffering from severe Post-Traumatic Stress Disorder. Unable to return to work due to the psychological trauma sustained during a failed rescue mission, an increasingly frustrated and volatile Theo's world is rocked when one morning, he wakes up next to his wife's murdered corpse with no recollection of what transpired and all evidence suggesting that he's killed her. When the police label him as the prime suspect, Theo goes on the run, and is soon being hunted by Deputy Chief of Police, Alan Shard, a notoriously ruthless soldier of the law, who is hell-bent on catching Theo as one last act of service before he officially retires. However, when an unknown third party is thrown into the mix, Theo discovers an alarming connection between the sinister forces hunting him in an attempt to silence him permanently for a reason he can't comprehend; and a recent investigation his wife was conducting into a global armament contractor. When connecting the dots becomes a matter of life and death, Theo becomes embroiled in a desperate fight for survival and must figure out who really murdered his wife before a terrifying conspiracy changes the course of a nation forever.
观众对《血偿2021》的评价两极分化，一方面认为剧情离谱、演员表现惊艳，另一方面认为编剧粗制滥造、剧情不合理。
它是一部值得一看的电影，通过其故事和表现手法，让观众反思剧内向观众表达的意义和人性的复杂！
这是一部非常特别的影片，没有大开大合的剧情，没有博人眼球的类型元素，没有贯穿到底的故事脉络。像是一杯温开水，看似平淡，却喝起来十分解渴。
说真的，《血偿2021》看完后我真的是久久不能平静！因为这部影片确实带给人的震撼太大了！不论是剧情节奏，还是剧情尺度，都让人不敢相信这是其它剧的水平。
充满了各种自相矛盾的观点，以及对人性的各种颠覆解读，看一遍绝对不过瘾。你每刷一遍，都能对人性有新的认知。
