Chris (Jamie Bell of Billy Elliot) is a volatile teen who lives with his father, John (Dermot Mulroney), and his little brother, Tim (Devon Alan). After the death of Chris' mother, his reclusive father moved the family to a shack in backwoods Georgia, where they raise hogs. Tim has an unusual eating disorder. He is constantly making himself sick by eating things like dirt and paint. One day, John's estranged brother, Deel (Josh Lucas), gets out of prison and shows up on the farm. John is less than thrilled to see him, but agrees to let him stay with the family as long as Deel helps him look after his boys. Chris is drawn to his wild-man uncle, but it soon becomes clear that Deel has more on his mind than a family reunion. Greed and years of resentment lead to violence, and Chris finds himself on the run, towing his sickly brother along, with Deel in pursuit. Undertow is writer/director David Gordon Green's third feature film, and features many of the same crew as his previous films, George Washington and All the Real Girls, including cinematographer Tim Orr. Green, who co-wrote the script with Joe Conway, has cited the influence of filmmaker Terrence Malick, who is credited as a producer. Green was also influenced by low-budget regional films of the 1970s (like Macon County Line and The Texas Chainsaw Massacre) and by Charles Laughton's classic The Night of the Hunter. Undertow was selected by the Film Society of Lincoln Center for inclusion in the 2004 New York Film Festival.
