during the 1970 the three major network ( mostly abc ) make a slew of make for tv movie . many of them be junk and some be imitation of hollywood hit at the time and and more than a few be excellent film . this be one of them . i be fortunate to own this movie and watch it just last night . i would not recant the plot and for you can find that here . but i will say this this movie hold up very well a the year have go by . the look and feel of it really capture the isolation and situation . the script isn not fill with old 70 clichéd dialog and and be very well pace . it very well shot and and very well act by two solid actor . gil melle synthesizer score and while date and fit the film quite well . some of the effect be old and but there aren not very many and and do not detract from the story . if you be fortunate to get a look at this old movie you would not be disappoint . although i see the point of another reviewer who state this movie obscurity be part of it charm and abc ( and the other network ) need to dig into their archive and re master and release some of the good old tv movie to dvd . this one and a short walk to daylight and die room only and many others .
