Stay Over is a comedy of what can happen to you when trying to make up after an infidelity. Mark and Michelle, a thirty something couple, are settling in for an affectionate reconciliation on a snowy night in New York. Mark’s a bit of a rake, and Michelle had allowed him an outside affair, in the hope that he would “get it out of his system.” She relents on her tolerance when Lilly, the twenty-something dancer that Mark had dallied with, bursts into their apartment out of the snow, hoping to stay over.
