Remember Me  (Movie, DVD)

In 1991, an 11-year-old girl named Alyssa "Ally" Craig witnesses the murder of her mother on a New York City Subway platform, on the F Line at 18th Avenue and McDonald Avenue elevated station in Brooklyn.

Ten years later, a 21-year-old Ally (Emilie De Ravin) is a student at New York University. She lives at home with her overprotective detective father, Neil (Chris Cooper). Tyler Hawkins (Robert Pattinson), a moody, directionless 21-year-old, is auditing classes at NYU and working in a bookstore. He has had a strained relationship with his businessman father, Charles (Pierce Brosnan) since his brother Michael's suicide (after which Tyler got Michael's name tattooed on his chest). Charles appears to ignore his youngest child, Caroline (Ruby Jerins), with whom Tyler is very close.
