Yellowneck is a 1955 American Civil War film directed by R. John Hugh and starring Lin McCarthy, Stephen Courtleigh, Berry Kroeger and Harold Gordon.
It tells the story of five deserters from the Confederate Army who make their way past the Everglades and angry Seminole Indians, in an attempt to get to the Florida coast and then to Cuba.
When the Indian guide is found killed by Seminoles, the foursome reluctantly join forces with the Colonel in order to reach the coast and ride out the rest of the Civil War.
As the group treks through the dangerous Florida everglades, it's revealed that Plunkett has stolen a large amount of gold from the Confederate army, which Cockney wants to steal from him.
The group continues its trek, and it is revealed Cockney is drop-dead afraid of snakes, and being in close contact with them sends him into a paralyzed state.
Upon getting to the other side, Plunkett offers the Sergeant his gold (as he has provided his safety for the duration of the trip) and finds only rocks in his satchel.
