This is quite equivalent an 1980's Canadian lower budget film and it has the elements of those older, campy horror slasher films from that time period. The film starts with an apparent flashback scene but it's not evident until later, with a teenage girl killer her parents by poisoning their food. Nothing is explained why she did this. Then the film fast forwards to about twenty minutes later.
The film has a very slow build and is quite boring to start, including a bizarre overly long dinner scene with the lead couple and four of their friends.
The first half isn't great but we continue watching. The main central plot revolving around the escapee "Pyscho Girl" sister from the asylum poisoning these six people at their dinner house. The woman mentions being the sister of the maid so that's how she's able to get in the couples house.
From there, it really starts at the empty facility with each member being tied up and the three convicts committing different types of deaths kills to them. One involves slashing of a character's throat, another is an electrocuting in a bathtub, another a simple gun shot to the head. Eventually the lead man of the couple escape from being tied up and starts attacking them.
The final twenty minutes were easily the highlight as there were some gory kills and it becomes more interesting. A lot if silly decisions by the villains. But overall, nothing is really noteworthy or that memorable.
There is also narration throughout which completely takes away from the film.
