The nut doesn’t fall far from the family tree.

Jihadi John’s younger sister produced a short film titled “The Killer’s Footsteps” in school — featuring a hooded maniac, according to a report.

The 19-year-old, now a media student at Middlesex University, attended Quintin Kynaston school, where she studied cinematography, according to the Daily Mail

Her macabre film — which depicted a dead schoolgirl and a hooded, knife-wielding madman — was part of her coursework.

The woman, whom the Daily Mail has not identified, described the film as representing “a dangerous, shocking criminal who is a serial killer.”

She stressed, though, that her flick teaches that “revenge is never the right answer.”

“We showed and represented this killer by hiding this person under a hoodie, in dark or very dim light to create a mysterious atmosphere throughout the film,” she said. “By doing this we are able to play with the audience’s mind a bit, and show them that the fact this killer can be anyone … But who?

“This killer can be a friend, family member, teacher, or in fact someone they have never met before. However, the killer knows the protagonist and has been watching the protagonist.”
