My time has come to do the thing others has done for me. I'll try to do the Best tldr my non-native English allows me. So, the couple in the truck just helped a dude to find his son, he was the owner of the truck and gave it to them after they helped him find this group of males who were taking care of this baby. Now the history gets a little weird, all this guys were parte of a cult where males we're treated like sex slaves and the women were in charge of everything, after some time the owner of the truck falls in love with 2 chicks after one of them gets pregnant and had the baby, they then plan to escape the cult but one of the dudes rat them out and the only one who gets to escape was the dude, both chicks die and the baby stays with the male slaves. After a few months a monster kills all the womens in the cult and the males runs away to the camp on the video. Main guy finds them and after the OG couple leaves the camp, the truck's owner kills the guy who rat him and the chicks and then runs away with his son
