An elderly woman falls out a window to her death while babysitting for a little child. It looks like she tripped over his wooden blocks. Unable to look at them, the parents throw the blocks away and buy him new ones. Strangely, the old blocks return and start spelling out ominous messages of death. The father decides to get rid of the blocks once and for all by setting them on fire. The small driveway fire spreads to the house, killing the parents and the child.
It is soon revealed the the child's aunt bought the vintage blocks at an estate sale. Unknown to her, they have an evil history of Satanism.
In the burnt-out remains of the house, two pre-teens find the blocks seemingly untouched from the fire. One of them decides that his little sister would like them, so he puts the blocks - which spell out "FIRE" - into his backpack to bring them home.
