The X-Files Season 4

The prophetic words of the alien Bounty Hunter resonate throughout the fourth season, beginning with the near death of Mulder's mother and the murder of the mysterious X. Even the return of Alex Krycek and the alien black oil are overshadowed by Scully's cancer. Then the tragic reappearance of Max Fenig leads to the death of a fellow FBI agent. Yet even as these events strengthen Mulder's belief in a growing conspiracy, a startling truth revealed to Scully plunges him into a crisis of faith which could prove his ultimate undoing.
