saw this on TV in the early mid nineties as a kid (in colour, in the UK):
It begins with a boy hiding in a wardrobe who witnesses an intruder murder his parents as he watches through a tiny gap in the wardrobe doors. The boy somehow escapes and runs down a road, away from the house in the background, crying (possibly holding a stuffed animal/toy).
-Then the entire movie/tv show happens-
By the ending, the boy is now a cop(/law enforcement) investigating something at his childhood home when he is attacked/gets into a serious fight. It ends with the same shot of the boy (now a man) running away from the house holding a bloody wound, echoing the beginning scene (book-ended mirroring scene)
