Hell's Heroes (2014)

After a foursome rob a bank, killing a clerk and losing a crew member in the act, they flee into the desert. While wandering, they stumble upon a woman in labor. Before she dies giving birth, she makes them promise to bring the baby to its father -- the man they killed at the bank. Robert (Charles Bickford), after he loses his other two accomplices, is determined to uphold his vow and save the child, but with limited resources and the law on his back, his odds of success aren't good.
