TAC braces for an un-jolly Christmas when Bull and Benny represent Marissa and her estranged husband, Greg, in federal court after they're charged with money laundering and fraud connected to Greg's restaurant. As Bull and Benny defend the divorcing couple together so the prosecution can't use them against each other, they search for jurors who will believe Marissa had no knowledge of Greg's business dealings. Also, as Bull and Izzy prepare to baptize Astrid before the Christmas holiday, they reach an impasse regarding what they want from their renewed relationship.

Bull and Chunk represent an emergency room doctor being sued for malpractice after she ignored direct orders to save one near-death patient in favor of helping another who was also critically injured. As voir dire begins, they look to select jurors who can consider the idea that their client made the best decision possible amidst an impossible situation.
