Almost everything about Wallace, an introverted African-American transplant from Alabama, is at odds with the lakeside Midwestern university town where he is studying for a biochem degree. For reasons of self-preservation, he has kept a distance even from his own friends - some dating each other, some dating women, some feigning straightness. But a series of confrontations with colleagues, and an unexpected encounter with a young straight man, conspire to fracture his defences, while revealing hidden currents of resentment and desire that threaten the equilibrium of their community.
