A family purchases a home robot designed to look like a grandmum. Their neighbours immediately buy a more expensivve model as the two families always try to up the other one. Both grandmums start to "terorize" their families because they were set up to ensure the mums exercise, the kids study etc. Apart from that they start causing problems to the other family ... cut ropes with hanging clothes, pierced tires, etc. Once they get to killing each other family's pets the parents get really worried about the safety of their kids. The grannys later destroy each other while fighting and the families decide that they'll be better off without any robots. (It's some time since I saw this so the details may be off.) Mainly thanks to the design of the robots it's rather a comedy than a horror. Unless you are ten. And a rather good comedy!

A remake of Vávra's 1948 atomic age thriller Krakatit.

Sunday in September 1977, a celebration of the Miners Day. The old Hepnar is sitting at the cemetery and is recalling events from ten years ago. That time the representative of the ministry Barvír announced at the miners meeting that mining in the mines would decrease. He reasoned this decision by the fact the deposits of coal are almost used up. The boss of the mine and most of the miners protested. Barvír did not take their critical objections into account. He announced at the communist district meeting the closure of the business as the mine according to new economic principles did not prosper.
