Vahid, an Azerbaijani auto mechanic, was once imprisoned by Iranian authorities. During his sentence, he was interrogated and tortured blindfolded. One day, a man named Eghbal enters his workshop. His prosthetic leg creaks, and Vahid thinks he recognizes one of his former torturers. He kidnaps Eghbal to get his revenge, but soon doubts arise as to whether Eghbal really is the monster that Vahid suspects him to be.
