Righteous Kill

Two cops on the verge of retirement, David Fisk (Robert De Niro) and Thomas Crown (Al Pacino) are pulled back in to handle one last case. They are to solve a brutal murder of a pimp. Things are not what they seem though as this case appears to be similar to a case they worked on years earlier. A poem is left at the scene of the crime just like the murder they thought they had already solved. It also becomes clear that the serial killer may not be entirely evil as the murders are from cases that have been unsuccessful in court. An ethical dilemma also develops as the cops feel they may have mistakenly arrested the wrong man the first time around.
