Picture strangers breaking into your house in the dead of night.
It's a frightening thought. The safe space of the home is violated - the one place you're always supposed to feel comfortable, secure and free of the dangers of the outside world.
Such a violation is bound to leave you feeling anxious, paranoid and suspicious.
It's this scenario which is explored in Netflix's latest thriller, Intrusion.
The snappy film - which barely cracks an hour and a half in runtime - stars Freida Pinto (Slumdog Millionaire) and Logan Marshall-Green (potentially still best known for his memorable turn as Trey Atwood in The O.C., but also the star of Upgrade) as married couple Meera and Henry Parsons.
The pair have recently moved to a tiny, remote New Mexico town, far removed from their lives in Boston, Massachusetts.
It's clear they're a successful couple, with their enormous, modern home springing out of the desert landscape.
Meera is a child psychologist and Henry is an architect - and it's clear from the get-go that both have things to hide.
Fairly early on the couple come home to find that someone has trashed their house, and a few days later they endure a terrifying - and deadly - home invasion.
But when everything seems sewn up, Meera still has fears and doubts - and questions over her husband's odd behaviour.
While there are very few surprises to be found in Intrusion, and the audience barely feels any tension if what should be a very tense movie, the story is still halfway decent.
Both Pinto and Marshall-Green (decked out in 'nerdy' glasses and cardigans that should give off an unthreatening air, but rather achieve the opposite) deliver good performances.
The climactic scene, while expected, is still somewhat satisfying, though the coda leaves a lot to be desired.
Under the direction of someone like David Fincher or James Wan or even Jordan Peele, this probably could have been a really great movie.
But, as it stands under the direction of Adam Salky (I Smile Back), it's an exceedingly average way to spend 90 minutes.
