The third Sunday of every month is open house brunch at the Sheppard home. Travel circumstances leave Tom Hayden accepting an invitation from a stranger. One look at his hostess Corin with her husband unlocks buried emotions, reinforcing his failures. Leaving her is difficult, but he has no other option, taking with him the first line of a new song: She's another man's love, she'll never be mine. When the situation changes, the reality of their destinies must be put in perspective. Can Corin move forward without guilt? Will the reality of their relationship spoil the dream they've been fantasizing about?
