'Visitors From Down the Street' Prod Code '#104' by J. Michael Straczynski

The Excalibur picks up two very peculiar guests: a pair of paranoia-ridden aliens named Durkani and Lyssa, who are determined to uncover their government's secret extraterrestrial cover-up, and insist that humans have been meddling in their planet’s affairs for decades. But Captain Gideon is in no mood to paticipate in someone else's paranoid conspiracy fantasy…
