Agent Doggett is suffering amnesia and is wrapped up in smuggling ring, getting illegals across the Mexican border. Mulder and Reyes join forces to help find him.
If there is no struggle, there is no progress. Those who profess to favor freedom, and yet depreciate agitation, are men who want crops without plowing up the ground. They want rain without thunder and lightning. They want the ocean without the awful roar of its many waters. This struggle may be a moral one; or it may be a physical one; or it may be both moral and physical; but it must be a struggle.
