Passion and Prejudice (2001)

When prim and proper New England college professor Gwen Barry (Titanic's Frances Fisher) hires handsome young prison inmate Dalton Roy (Derwin Jordan) to tend her yard through a prison work furlough program, their mentor-student relationship soon turns into a passionate love affair. But when Dalton completes his prison sentence, meets a pretty young college student (Kandyse McClure), and attempts to start over again on his own, Gwen becomes obsessed with remaining a part of Dalton's life or destroying it completely.
