Bashir's Cardassian friend Garak (
Andrew Robinson) is slowly and painfully dying from an apparent brain tumor. It is soon revealed that the source of Garak's agony is actually a brain implant, the handiwork of the Cardassian intelligence agency Enabran Tran. Bashir's efforts to save his friend are stymied by Garak himself, who has become addicted to the implant and becomes violent whenever anyone approaches him. Written by Robert Hewitt Wolfe, "The Wire" originally aired May 7, 1994. ~ Hal Erickson, All Movie Guide
