For Scorpion agents Day and Knight, their relationship is slow to develop, and trust is hard to build. Then Day's brother, Stephen, goes missing, and Day finds out more about him than he ever dreamed. Day's first reaction to Stephen's disappearance is to try to get to him as fast as possible. Knight initially holds him back so they can attempt to find out what they're walking into. But when Knight sees Day's desperation, he steps in to help and tries to calm the man he's growing to care about, even though the trail is cold and clues are scarce. When Day witnesses his brother being shot live on television, he loses the last of his control. Despite the lack of answers, Day is more determined than ever to find out what happened. Stephen was all the family he had left. Bone-deep fear and adversity threaten to tear Day and Knight apart, but facing unimaginable hardship together might finally cement the bond between them.
