The Darkness and the Light (Star Trek: Deep Space Nine)

"The Darkness and the Light" is the 109th episode of the television series Star Trek: Deep Space Nine, the 11th episode of the fifth season. It premiered on January 6, 1997.

Set in the 24th century, the series follows the adventures of the crew of the space station Deep Space Nine near the planet Bajor, as the Bajorans recover from a decades-long occupation by the imperialistic Cardassians; although the occupation precedes the timeline of the series's narrative, many episodes explore its history and consequences. This episode focuses on the station's second-in-command Kira Nerys and her history as a member of the Bajoran resistance movement during the occupation, as a murderer is targeting Kira's comrades from the resistance.
