Mulder and Scully head off to Alaska when the scientists working on the Arctic Ice Core project have seemingly gone crazy and killed each other. The project team had just beaten the record for the deepest core sample when they soon began to act oddly. Along with two scientists and a helicopter pilot, the agents arrive at the deserted post and soon find that an ancient micro-organism from one of the deep core samples is responsible. The helicopter pilot is the first affected and has to be restrained. One other of the group is also infected and the chief scientist in the group thinks it's Mulder. Written by garykmcd

Cold Aggression
20 September 2006 | by thebigeasy555See all my reviews

A true stand out episode from season 1 is what Ice is.An artic location,claustrophobic conditions and a general feel of paranoia looming in the freezing air makes this is a must see episode from season one.The previous occupants of the artic station Mulder,Scully and four others go to have either killed each other or killed themselves.A virus is bringing out murderous aggression and is responsible for bringing out deadly paranoia and fear.Mulder and Scully actually begin to question each others sanity.Tension is that high.The writers have to receive great credit for creating that sort of scenario where the atmosphere is so tense Mulder and Scully come into conflict in such a direct manner
