I Robot [2004 PAL DVD][En Multisubs[8]

It's the year 2035, and the society now has the help of robots. These robots follow three laws integrated into their system; 1) They cannot harm a human being or, through inaction, allow a human being to come to harm. 2)They must do whatever they're told by a human being as long as such orders don't conflict with law one. 3) They have to defend themselves as long as such defense doesn't conflict with laws one or two. One day, the writer of the three laws, Alfred Lanning, apparently jumps out of a window at U.S. Robotics. The majority of the Chicago Police Department believe he committed suicide, but Detective Del Spooner, who hates robots, thinks he was murdered, and the number one suspect is a robot who calls himself Sonny. However, if it was Sonny, then it means he would've had to have broken the three laws. With the help of Dr. Susan Calvin, Spooner must now discover the truth before it's too late.
