whenever any conversation about creepy film come up i always mention this one . those who have see it scream that film be incredible . while the rest want to know the plot . well the plot be very simple but even so undeniably intrigue . a couple stop at a petrol station and she go in to get coffee . she never come out . that it . what then happen it that we see the third person involve in her fate and this be why the film really get under your skin . it the sheer normality of this character who constantly have to push himself and test himself to see how far he can go . this be the only film i have ever watch which have actually give me a sleepless night . i end up pace the flat unable to forget about the fate of the character in my head . unusual yes but this film really do give one nightmare . i saw it in 1991 and i have not see it since . i do not particularly want to because i can still remember it vividly 16 year later . it really do not get any more effective than this . a real gem but keep it at arm length . it a killer .
