Mud (2012)

Two teenage boys in the Arkansas delta, Ellis and Neckbone, travel to a small island in the Mississippi River where Neckbone found a boat stuck high in a tree, likely from a flood. They intend to make it their own. They realize someone is living in it and meet Mud – a fugitive who grew up in the area. He wants to reunite with his old girlfriend Juniper and then skip town. Mud explains he killed a man who had impregnated Juniper and then pushed her down a flight of stairs, causing her to lose the child. The boys decide to lend Mud a helping hand, working to free the boat and get it working again, in exchange for Mud's .45 pistol. Mud also tells them about Juniper, whom he claims to love. He describes her as having a nightingale bird on her hand, and Neck and Ellis spot her at the local Piggly Wiggly. When they follow her, they interrupt abuse of her by another man. Ellis charges the man and shoves him off Juniper, but is punched and gets a black eye. Juniper thanks Ellis for saving her.
