Two people live unlucky in love in Boston: Erin, whose activist boyfriend Sean has just walked out on their relationship to help a Native Americans in the United States tribe fight off a land development deal. Alan, a plumber struggling to pay off family obligations while pursuing a career as a marine biology. Both deal with personal and professional problems and stumble through relationships, continually crossing one another's paths without ever truly meeting and realizing how perfect they are for one another. Time and time again one almost catches the other's eye, but circumstances intervene. After a series of ups and downs both of their budding relationships with others crash and burn, just in time for a chance meeting on the Massachusetts Bay Transportation Authority train heading to Wonderland (MBTA station), on the outskirts of Boston.
