Valkyrie Drive: Mermaid (2015)

S02E19 One Hundred Miles a Gallon

When the son of one of Colt's buddies goes missing, Colt heads to South Carolina to track him down. However, he quickly discovers that the situation isn't what he expected; they aren't involved in moonshining as he assumed. To make matters worse, the usual drivers have also abandoned their posts, leaving Colt to navigate a more complex scenario than he bargained for.
