This is a wee duology of movies, so much so I could easily believe they were made at exactly the same time.
We start with The Locker, in which a group of college friends have a camping trip, and then strange things start happening to them... because of them also used a cursed locker! There was a discarded baby put into the locker, and now the baby is out for revenge on anyone that dares use it! There are six of them, and can you guess how many are alive by the end?
One of them was teaching a middle school student, who is whomst we follow in The Locker 2. She's warier of the locker, but others aren't, and so bad things continue to happen. We get one more line of lore (the baby was discarded 5 years ago) but otherwise this is just following more people and more deaths. Who will survive? Don't bet on it!
The same actors and locations, and being released in the same year, is what makes me think they were made at the same time, and given both are barely over 70 minutes, they really are a part 1 and part 2.
There is somewhat of a slow build, with enough strange things happening to keep you interested. There are a few weird death effects, but mainly people being pulled into nothingness (very Ju-on reminiscent).
A double feature if you want a full film, but ultimately nothing that impressive these days.
