On a weekend otherwise notable for season finales, a small documentary film festival breaks out on the upper reaches of basic cable.

Departing from its usual freakish fare, TLC offers the documentary “Off the Rez” (8 p.m., TLC). Directed by Jonathan Hock and produced by Kelly Ripa and Mark Consuelos, “Rez” follows Shoni Schimmel, a Umatilla Indian who is considered one of the best high school basketball players in the country. Coached by her mother, Ceci, Shoni’s prowess on the hardboards may allow her to be the first in her family to leave the reservation and attend college, a dream that is at once filled with personal promise and cultural disorientation.

• A little further up the cable tier, the arts-related Ovation network offers “Con Artist” (8 p.m., Ovation), a documentary profile of controversial artist Mark Kostabi. Inspired by Andy Warhol’s notion of a pop art “factory,” Kostabi hired a revolving army of assistants to mass produce works bearing his name. A darling of the art world who has since fallen out of favor and into money woes, Kostabi’s career seems to have been an effort to see just how long and how far he could take a rather self-evident put-on. The film’s title comes from a quote from Kostabi himself: “Modern Art is a con and I am the world’s greatest con artist.”

• And finally, the documentary “Ghost Bird” (7 p.m., Documentary Channel) looks at the excitement in a corner of Arkansas after the reported sighting of an ivory-billed woodpecker, a species considered long extinct. The Documentary Channel is available on select cable systems and on both Dish and Direct TV satellite providers.
