Astro-physicist Matthew Dansk falls for one of his colleagues during a research trip, but Matt is looking for a serious relationship and he doesn't date men who are in the closet. Alan has no interest in letting anyone find out he's gay and he never goes out with the same man twice. When the two men part ways, Matt believes their situation is hopeless, and he does his best to forget his feelings for Alan. Months later, Alan winds up in the hotel room next to Matt's at a conference, and both men realize the chemistry between them hasn't diminished. As they spend time together, Matt sees a different side of Alan. When he realizes Alan's feelings for him run deeper than he'd thought possible, he begins to hope that they can be together after all.
