Precipice is an episode of the TV series, Battlestar Galactica, and aired during the show's third season.
In response to the suicide bombing of a New Caprica Police (NCP) ceremony, the Cylons order a crackdown against the insurgency. Many resistance members start to disagree about the legitimacy of the suicide bombings, but leader Colonel Saul Tigh (Michael Hogan) continues to orchestrate them. In an attempt to get Kara "Starbuck" Thrace (Katee Sackhoff) to love him, Leoben Conoy (Callum Keith Rennie) presents her with a toddler named Kacey (Madeline Parker), whom Leoben claims Starbuck is the mother, having been born as a result of her time on Caprica in "The Farm". Leoben leaves her alone with the toddler, but Starbuck refuses to play with her. When she leaves Kacey unattended however, Kacey injures herself falling down the stairs. As Kacey is recovering, Starbuck has a change of heart and prays to the Lords of Kobol not to let her die.
In a move against the insurgency, the Cylons decide to have the NCP arrest 200 civilians they believed to be affiliated with the resistance. Headed by James "Jammer" Lyman (Dominic Zamprogna), most of the arrests take place during the night. Those being arrested include Laura Roslin (Mary McDonnell), Tom Zarek (Richard Hatch) and Cally Henderson Tyrol (Nicki Clyne). After another suicide bombing at a power station, the Cylons decide to have the prisoners executed, but require President Gaius Baltar's (James Callis) signature. When he refuses to sign, an Aaron Doral (Matthew Bennett) copy forces him to at gunpoint. Caprica-Six (Tricia Helfer) attempts to stop him, but Doral shoots her in the head. Baltar signs the document. Meanwhile, Ellen Tigh (Kate Vernon) learns from Cavil (Dean Stockwell) that he only released her husband Saul (Michael Hogan) because the Cylons know he is leading the resistance. He informs Ellen that unless she tells the Cylons where the resistance leaders will be meeting next, he will imprison Saul once more. Reluctantly, Ellen gets hold of where the resistance plan to meet with members from the colonial fleet.
On board Galactica, Admiral William Adama (Edward James Olmos) appoints their Cylon prisoner Sharon Agathon (Grace Park) to a Colonial officer and has her go to the planet to liaison with the resistance. When she arrives to meet with resistance members, Centurions arrive, having learned where they are from the intelligence Ellen provided them, and start attacking them. Simultaneously, the 200 human prisoners are being transported to a location by the Cylons and NCP. A masked Jammer, realizing they are to be executed, saves Cally by releasing her in secret and telling her to run. As she runs away, the sound of gunfire is heard.
