I remember few scenes:

theres a couple that the boy works in a garage that belongs to his girlfriend’s father. they go to a field and shoot a video about invitation to their distant town. you can see someone is murdered in the frame by a gunman. in the end, the serial killer project is to replicate a picture from the 30s, he stuffed humanes and dressed them in a 30s style and put them in a thing that looks like a vintage kitchen. thats all i remember pls help.
