Tim films his brother Sean's funeral after his suicide, then uncovers Sean's fixation with a nonexistent online urban legend about a failed government mind control experiment.
Kind of? "Sean was our angel, and God called him home early." Or something like that is said a couple times by the main characters mother whenever she talks about his death. She also mentions God in general a few times when on topic about Sean (in general, not just his death too)
Around the 55 minute mark, a mother animalistically crawls around on all fours to the children's bedroom with a knife. She crawls on top of one of the children's beds, and raises the knife. You can hear the kid yell out before she kills them, then the other children wake up and start screaming. :(
