The Daggers have been commissioned by NATO for the highest clearance missions possible following their success with the uranium project. After a scandal with a Weapons System Officer on the Dagger Squadron, Lieutenant Brooklyn "Sphinx" Kazansky has been requested to train alongside them as the replacement WSO for Jake "Hangman" Seresin. Brooklyn quickly realizes that she's the outsider with the Daggers and despite that, continues to include them throughout the holiday season for her family's festivities. As things cool down outside, they start to warm up between Brooklyn and Jake. Will they stay friends or will their time under the mistletoe move things to the next level?
