Sounds identical to Let Us Pray, really identical.
I'm still gonna give it a go this afternoon, though I can't possibly imagine Last Shift coming close to level of horror that was on display in Let Us Pray. Both films being released in 2014 can't say what script came first, but you can literally copy, paste and interchange the plot summaries from Last Shift and Let Us Pray and they would fit perfectly.
From Let US Pray: Rachel, a rookie cop, is about to begin her first night shift in a neglected police station in a Scottish, backwater town. The kind of place where the tide has gone out and stranded a motley bunch of the aimless ect. ect. ect...............and All Hell Will Break Loose!
Last Shift: A rookie cop's 1st shift in the last night of a closing police station alone turns into a living nightmare. The plot echoes John Carpenter's 'Assault on Precinct 13' but with supernatural twist.
Be back to make a comparison after the film...........
Well it seems that they are two very different films despite the synopsis. Last Shift is also a creepy, atmospheric horror flick. At times it suffers a little because it's just us and the lone cop as we are dragged from "one hallucination, or is it?" scenario to another(some scenes left with a question mark), but the last act was particularly tense and quite creepy. The ending was good imo, fitting. I could knit pick about a few things, but as a big fan of horror I'll be forgiving because I did enjoy the film overall. Worth a watch 6.5/10
