A grieving widow finds herself for a night she will never forget in this thriller from filmmaker Justin Groetsch.

Ida has been grieving since a house break-in led to the death of her husband Isaac. The only solace she seeks is her best friend, Katrina. When the two meet up at the local bar, Katrina makes Ida an offer to help take her mind off of things. Ida is offered a job as a night security guard in a high rise. Ida reluctantly takes the job and begins to work.

At first, things seem quiet. However, Ida soon sees strange messages on her phone from someone who claims to be her dead husband. She becomes warned that there are intruders in the building and soon enough, she sees two people decked out in black and sporting masks. Ida is convinced that Isaac is back from the dead to help her out of the situation as they are the same people responsible for his death. Can Ida be able to escape this night from the intruders or like Isaac, become their next victim?

A meshing of isolated horror, supernatural horror, with a dash of The Purge, Justin Groetsch’s film starts out with a bit of a bang, where our protagonist’s husband is murdered. The film then starts out with the setup and once we see Ida working in the building, that’s where things instantly begin to pick up. Starting with the supernatural elements, it soon becomes a fight for survival with the villains decked out in black and sporting masks that were inspired by the Blumhouse franchise where crime is legal for 24 hours.

Kudos must go out to Mikaela Hoover, who goes through a transformation from grieving widow to fighting for her survival as Ida. While we see her at first completely freaked out when she sees messages from her husband, who was murdered. It should be mentioned that writer-director Groetsch plays the husband in the opening scene of the film. It gives off a vibe where the ghost of Isaac attempts to help Ida evade the two invaders who were also responsible for her husband’s death.

The third and final act is quite a shock because not only was it unexpected, but it adds to one shocking twist after another while Ida tries to decipher why Isaac was killed and why she is the next one to be targeted. As we learn more about the situation, it adds to the mystique and shock value Groetsch intends to reveal by the end of the film.

Zero Hour starts out with a bang, slows it down for the setup, then gets intense from there on. Justin Groetsch’s script takes some very shocking twists in the third act. Mikaela Hoover shines in the lead role here and definitely needs to be seen here.
