a team vary between scully and mulder and two other scientist and a pilot and and the guy who play bana on seinfeld and go up to an arctic research post where all member have die off by either kill each other or kill themselves . they discover there a worm a virus that be parasitic to the point of madness and death . the problem be and after a certain dog lash out and anyone could be infect and but who . this be not just my favorite episode of season 1 and but also one of my favorite from the show . the arctic environment enclose the character and and of course like carpenter the thing and it a lot of fun watch these even temper character suddenly start to flip out in dramatic scene . and the visual effect of the worm and it effect under the skin be cheesy and i do not mind them at all . the drama between the character end up work more than it would usually because of the tension and because all of the actor ( include the bana guy ) understand what go on in the story . and and a usual and i love the ambiguity of the end . highly recommended .
