Birdman of Alcatraz

How does bitter convict Robert Stroud cope with a lifetime of solitary confinement? The answer, in a sense, comes from above in the form of a feeble sparrow he finds in the isolation yard. Stroud brings this newfound companion to his cell, nurses it to health and, from that point on, there's no turning back. Despite having only a third-grade education, and no hope of parole, Stroud becomes a renowned ornithologist and achieves a greater sense of freedom and purpose behind prison walls than many in the outside world will ever know.
