As former NSA, Dayton (Day) Ingram has national security chops and now works as a technical analyst for Scorpion. He longs for fieldwork, and scuttling an attack gives him his chance. But his opportunity comes with a hitch -- a partner, Knighton (Knight), who is a real mystery. Former Marine Knight crawled into a bottle after losing his family. After drying out, he's offered one last chance: along with Day, stop a terrorist threat from the Yucatan. To get there without drawing suspicion, Day and Knight board a gay cruise, where the deeply closeted Day and equally closeted Knight must pose as a couple. But after drinking too much, Day and Knight wake up in bed. Together. As they near their destination, they must learn to trust and rely on each other to infiltrate the terrorist camp and neutralize the plot aimed at the US's technological infrastructure, if they hope to have a life after the mission. One that might include each other.
