Teliko

On an international flight from Burkina Faso to the United States, a black man goes to the toilet, where he is attacked by a man with an albino appearance. Another black man comes out of the booth and goes to his seat. After a while, the flight attendant discovers the corpse of a man with depigmented skin in the toilet.

Three months later, assistant FBI Director Skinner, in the presence of Dr. Bruin, an employee of the us Centers for disease control and prevention (CDC), informs Dana Scully about the recent kidnappings of four African-American men in Philadelphia. One of the abductees, Owen Sanders, was found with signs of depigmentation, and a CDC official suspects the man died of some kind of illness. At the morgue, Scully discovers seeds of an unknown plant on Sanders ' body, which she sends to the FBI lab for analysis. Mulder flies to new York, where he meets with UN employee Marita Covarrubias, who informs him about the incident on the plane three months earlier.

At night, at a bus stop, an African immigrant named Samuel Aboa kidnaps a young African-American man named Alfred Kittel, immobilizing him with a poisoned arrow. At home, Aboa takes a sharp-tipped tube from his throat and inserts it into Kittel's nose. In the morning, Mulder finds the same seeds that were on Sanders ' body at the bus stop. On a tip from Covarrubias, agents begin to compare the lists of people who arrived on the plane where the man was killed with the lists of immigrants who applied for a residence permit in the United States. Marcus Duff, an employee of a social service, AAA help with the paperwork, gives agents the address of a client. The agents try to talk to Aboa, but he escapes and mysteriously hides in a narrow ventilation shaft in the wall of the house. The agents discover him and take him to the hospital, where it turns out that Aboa is completely healthy.

Mulder meets with Deabreu, a diplomat from Burkina Faso, which is ordered to conceal information about the dead passenger aircraft. Debra tells him the legend of his people about the Teliko Bambara – night "spirit of air". Scully, after examining Aboa's x-rays, discovers that he is missing the pituitary gland. Mulder concludes that Aboa removes the pituitary gland from its victims to make up for the lack of melanin in its body, causing the victims ' skin to discolor. Aboa escapes from the hospital, hiding in a food cart, and meets Marcus Duff in the Parking lot. After tricking Duff, Aboa immobilizes him and takes him to a construction site, where he inserts a tube into his nose. A police officer accidentally finds Duff's body with a pipe in his nose, scaring Aboa, who is hiding in a drainpipe. In search of Aboa, whom Mulder believes to be the mythical Teliko, agents arrive at the construction site at night, as an FBI lab employee, agent Pendrell, found traces of asbestos on Sanders ' body. Scully finds the discolored corpses of African-Americans in the ventilation of a building under construction, and Aboa paralyzes Mulder with a poisoned arrow. Scully finds Mulder and severely wounds Aboa with a gun as he tries to attack her.

In the report, Scully writes that Aboa's condition is severe, and its physical features have yet to be discovered by science.
