After one schoolgirl is raped while taking a short cut through the local woods, and another is murdered in the same woods a few days later, the local police are baffled. With the help of a reporter from one of the local papers, and against the wishes of a psychologist at the local hospital, a young teacher at the school the girls attended uses herself as bait to lure the perpetrator out. Could it be the creepy husband of the head mistress at the school, the psychologist who seems to be taking an unusual interest in the case, or something altogether more sinister?
Desde a “Aurora do Homem” (a pré-história), um misterioso monólito negro parece emitir sinais de outra civilização, assim interferindo no nosso planeta. Quatro milhões de anos depois, no século XXI, uma equipe de astronautas liderados pelo experiente David Bowman (Keir Dullea) e Frank Poole (Gary Lockwood) é enviada ao planeta Júpiter para investigar o enigmático monólito na nave Discovery, totalmente controlada pelo computador HAL-9000. Entretanto, no meio da viagem, HAL-9000 entra em pane e tenta assumir o controle da nave, eliminando um a um os tripulantes.
