Ceux qui restent

At a New England prep school, a curmudgeonly instructor (Paul Giamatti) is forced to remain on campus during Christmas break to babysit the handful of students with nowhere to go. Eventually he forms an unlikely bond with one of them -- a damaged, brainy troublemaker (Dominic Sessa) -- and with the school's head cook, who has just lost a son in Vietnam (Da'Vine Joy Randolph).
