Older ladies behaving badly is a fun and entertaining trend. This one is quite over the top with the body count quite high. A woman pretends to be the grandma of a woman who lost her mom recently. Friends and loved ones are sceptical. It's quite fun as she insinuates herself into her victims life. Not a lot of explanation for the psycho behaviour though. The other recent similar Lifetime thriller "Killer Grandma" was slightly better.
