Occasionally known as La Casa 3 and is allegedly a sequel to Evil Dead because there's no law against doing stuff like that in Italy  and this is a painfully Italian horror made by Umberto Lenzi under the name Humphery Humbert, it stars some unknown people who no doubt tried their best but in true Italian horror style, consistency, plot and continuity are merely polite suggestions.
One interesting fact is the father of the creepy child antagonist was Alain Smith, a well respected theatre actor from the Isle of Wight. I would love to know how he ended up here.

I hear there was a time in the 80s when Italian production houses believed that making their staff and characters have uber American names would ensure a better chance of success and so we have our first characters named Sam Baker, his un-named wife who we will call Ma Baker and their daughter, Henrietta
It is Henrietta's birthday and she's celebrated by slaughtering the family cat with a pair of scissors however not a drop of blood has made it onto her pristine white dress or shoes, continuity gaffe or a hint she didn't do it, who knows?
Anyway, Sam dooms Henrietta to the basement for this act. She sits in the dark and hugs her ugly clown doll that plays a song I shall call Hells Lullaby ⟨™⟩
Sam goes upstairs and tells his wife he's worried because the kid was perfectly normal and now she's killing cats. Sam thinks Henrietta is under a spell or a curse and has no idea how this has happened.
Ma Baker seems to think Henriette being a child and their only child to boot that killing cats should just be overlooked as some kind of youthful folly,

Sam changes a lightbulb and it explodes right as Hells Lullaby ⟨™⟩ starts up, he picks up the shards bare handed as one does and an advancing withered hand with an axe smashes a coconut that the movie is trying to pass off as Sam's head, Ma Baker comes to see what the commotion is, sees her dead husband and then a slowly morphing mirror explodes, gouges her eye and then the withered hand cuts into her neck with a knife, after all this we see Henrietta back in the basement with her ugly doll, she hugs it and looks sad.

We time skip to 1988, Martha and Paul are college students with an enormous open plan apartment on the Boston harbour, the lastest in 80s HAM radio technology and a car, they're managing this on Martha's wage as a part time docent...somehow.
Anyway, Paul tells Martha he picked up a radio transmission of a man freaking out and it's eating at him. Martha reckons it's a prank but Paul won't let it go so he tunes in again and hears the same message along with Hells Lullaby ⟨™⟩ so he presuades Martha to come with him so he can find the location and put his mind at ease.
The house is the same house used in House by The Cemetery as well

They find the owner of the message along with his friends, they are haunted by Henrietta and attacked by Dr Butcher from Zombie Holocaust multiple times before finding out Sam was an undertaker and pilfered that ugly clown doll from a corpse. This seems to be the genesis of the curse but it does NOT explain the climax of the movie where someone wearing a skeletor costume circa the Masters of the Universe movie holds up a knife and we can see it’s a skeleton with a robe covered in maggots. Who is it supposed to be? Death? The original doll owner? The evil that inhabits the doll?
Also when Paul opens Henrietta's coffin to torch her and her doll but she's not rotted in, like, 20 years.

As for wrap up, we hear the police lieutenant on the scanner telling the DA that Dr Butcher was responsible for all the murders, he tells Paul he now pretty much believes them about what happened but the public don’t want to hear about anything supernatural.

Paul says they’ll never see Henrietta again;

“Who was she?” asks an unmurdered character

“Just an ordinary little girl until her father gave her that doll and that’s where it all started”

Paul says…like that’s an explanation.

Okay this film is far from perfect but so are many of the so-called perfect ones. The score is beautiful, haunting and fits well, the composer went on to do a lot of porn but anyone who can score a movie called 120 Days of Anal deserves some credit, I mean, where does one even start with knowing how to score something like that?

The clown is creepy as hell and Henrietta is unnerving without actually doing anything.

The story is disjointed but you can tell there’s a lot of deleted scenes, one thing I did find that kind of explains a lot is apparently in Italy it is a custom to bury the dead with an item they loved to stop their soul wandering the world after death, perhaps the hooded figure that confronts Susan is actually the dolls previous owner? That would explain why it, the doll and Henrietta disappear at the same time.

Although the doll reappearing at the end is kind of a cop out and I’m sad the two sequels were in name only as I’d love to have seen more creepy clown doll shenanigans.

Perhaps though it’s perfectly fitting for a movie that was a fake sequel itself.


Interesting Stuff:

A police lieutenant says “The Baker's eleven year old daughter Henrietta, therefore she was having her eleventh birthday in May 1967

Her grave reads 1938 to 1967

Even if, as some say, it reads 1958, that’s still a big mistake

It also says Henriette…everyone, literally everyone says Henrietta.

Does eleven year old Henrietta being twenty nine year old Henriette count as a twist?

I’d say it was the wrong grave but there’s a picture in a cameo on the grave and it’s the same kid

That’s extraordinarily sloppy and I watch some bad movies

The credits, maybe they’ll say Henrietta or Henriette…no they say Henriett…what the fuck!

They also list Lieutenant Ferguson as Lieu Tenent, like that’s his name
