Undisputed III: Redemption. Years have passed since Yuri Boyka suffered a humiliating defeat and a broken knee at the hands of George 'Iceman' Chambers. Humbled by his injury, he has relegated to becoming the prison janitor. Meanwhile, mob boss Gaga has expanded his prison tournament enterprise into an inter-prison tournament called the Prison Spetz Competition (PSC), which gathers the best prison fighters from around the globe to compete for a chance at a cleared record and early release. Boyka begins training privately to bring his knee back into fighting shape. Boyka is transferred to Gorgon prison in the Republic of Georgia where he is joined by a diverse group of eight international prison fighters. Though the fighters are allowed one hour each day for training, they are still grouped into the general population for hard labor while Colombian fighter and local inmate Raul 'Dolor' Quinones is given private sparring sessions and a regimen of performance-enhancing drugs.
