The film begins with five friends who are organizing a weekend camping trip to a Missouri lake.
[1] As the friends set off for the weekend, Jake (Jasun Hicks) has a heated discussion with his mom over video relay service (VRS) using his iPad.
Cliff (Timothy Dillard) is watching and is fascinated by the speed of Jake's signing and seems unaware of the nature of the conversation.
Cliff identifies as hard-of-hearing and has only recently begun learning ASL as he was brought up orally and was mainstream schooled.
Keith (Will Sanders), the hearing guy, gets annoyed with him and Cliff wanders off to the other side of the fire where the deaf men are chatting.
The two deaf guys, Matt (Christopher B. Corrigan) and Jake, chide Cliff for trying to be part of the hearing world, while they were laughing at him.
A CODA, he has distanced himself from Matt and his deaf parents; his new wife had taken their calls and told them that Drew was not in.
His wife has never learnt to sign, and it seems that she has played a part in Drew's disconnect from the rest of his family.
Instead, Jake goes to the truck where Cliff and Matt learn that he has brought his late father's rifle along on the trip.
The brothers Matt and Drew escape from the house, along with Keith by taking a diesel Jeep and push-starting it.
Drew is saved by his brother Matt, who shoots and kills the owner but is injured in the process.
It transpires that the vast majority of people on the planet had been deafened by a cosmic event known as the "Soundfall".
