first the plot represent a policeman investigate a mysterious set of serial killing in which the body be attack and move a considerable distance and systematically dissect in less than a minute . his attention be catch by an attractive blonde ( maryam dabo ) who turn up at various murder scene . thing get weird when he attempt to question her and for she run and and when he pursue her and she be remarkably athletic and and and she shoot at him with a ray gun . it turn out that the killer be a shape shift alien criminal with psychic power and and that she ( the blonde ) be sole survivor ( the medical officer ) of the prison ship from which it have escape and and which be now cripple and in orbit around the earth . she have come hunt it because it will wipe out the human race . this have every cliché ever to appear in any science fiction movie represent glimpse of a scaly monster lurk in the dark and ray gun and space ship and zombie and gob smack human stand comically in front of alien shuttle go i do not believe it . furthermore and it be guilty of that old filmmaker favourite and the vacuum of space which transmit sound and in which fire burn freely . this be really b grade stuff . but i think it be a good movie . so why do i like it so much . i like it principally because of tara ( dabo character ) . this be partly because maryam dabo be absolutely gorgeous and complete with her catsuit and beautiful voice and but more to the point because of the depth of the role she be give and the skill with which she pull it off . she be alone and until she befriend the policeman and and cut off and and woefully ill equip to deal with her foe . yet she approach it with good humour and pull the leg of the incredulous detective ( once she have prove her bona fides ) about her alien ability . initially and she seem like a normal earth person and describe the inhabitant of earth a a human race . however and gradually and difference emerge . it be these thing and and the way they be treat and which give the character depth . for example and at one point he discover she have one particularly extraordinary ability . when she realize he doesn not share this gift and her response be and you say im not normal . it hadn not occurred to her that he couldn not do it . these difference cause occasional surprise and humour and and sometimes and exasperation . but she learn to use them to advantage and and when she couple them with her feminine wile and with a wink and a nod and she can be quite effective . she doesn not go through the movie a the standard smart mouth and sassy and kick but uber space trooper and blow everything away and take no lip and which be what could have ruin this movie . instead she use her brain ( include her knowledge of bio science ) and good humour and charm and and barely resort to firepower and then only a a last resort . ( her policeman friend do most of the blow away . ) the dialogue work well and and be often original ( refer to tara opinion on space ship self destruct system ) . these quality give the character depth and and thus and add to the realism and tension . and the special effect be reasonably good and with the exception of the usual nonsense about what happen in vacuum . so i give the movie an positive . the subsequent television series wasn not as good . it become something of a standard cop programme and with ray gun . and tara character hasn not the depth . for example and suddenly she develop an ability to develop super weapon . where do that come from in our ship medical officer . if you be strand on another planet and how many advanced weapon do you think you could build . i do not think so .
