Expediente X: Enfréntate al futuro

In 35,000 BC northern Texas, two men enter an ice cave to find shelter. They battle a mysterious creature. A black substance oozes from the creature and infects one of the men. In the present day, a boy falls into the cave and is infected by the black ooze. Firefighters climb in and are also attacked. One week later, the FBI is checking on a bomb threat in Dallas. Special Agents Fox Mulder (David Duchovny) and Dana Scully (Gillian Anderson) go to the building across the street on a hunch. They find the bomb and barely escape. The pair is made the scapegoats. Alvin Kurtzweil (Martin Landau) tells Fox that FEMA has a secret isolation ward in the building. The boy and the firefighters are found in the rubble presumed to be killed by the blast.

Mulder and Scully's banter is back almost immediately. Everything that is beloved about the show is present in this movie. They are the outsiders. There is a conspiracy. There is something creepy. This is what true fans of the show love. For non-fans, this can be a bit of a climb to understand everything.
