The Motive (TV Miniseries) (2020)

On a wintry Friday night in 1986, 14-year-old "A" woke up in his home in the Jerusalem neighborhood of Ein Karem. He took the M-16 rifle that his father brought home from the army reserves and shot his parents and two sisters in the head, point-blank. Then, he changed his clothes and ran to the neighbor's house. When the police arrived, the detective asked him why he had shot and killed his family. The boy answered that a green creature commanded him to do so. Hundreds of psychiatrists from Israel and abroad tried to decipher this abnormal act, but none could reach a clear conclusion.
