The pilot of this web series functions like a cold open would in a television series. You can barely call it a set-up. We see a character in a situation, and just as we get a wider angle—literally and figuratively—it’s over. The protagonist, whose name as far as we know, is “Mom,” is dozing on a couch in a messy living room. Her child is operating a handheld video camera while trying to wake her up, but she shoos him away. Then, somehow, she is inside a container not much bigger than a coffin. Saying any more would be a spoiler. As a pilot, this is light on exposition, big on suspense; great combo.
