Like Futrelle's other short stories, "The Problem of Cell 13" features Augustus S. F. X. Van Dusen as the main character, although most of the story is seen through the perspective of a prison warden. While in a scientific debate with two men, Dr. Charles Ransome and Alfred Fielding, Augustus, "The Thinking Machine", insists that nothing is impossible when the human mind is properly applied. To prove this, he agrees that he will take part in an experiment in which he will be incarcerated in a prison for one week and given the challenge of escaping. He achieves the goal with great ingenuity, and aid from his frequent confederate, newspaper reporter Hutchinson Hatch: after noticing rats in his cell escaping through a narrow drainpipe, he deduces that the pipe must terminate outside of the prison complex. He attaches a thread to a rat and a message addressed to whoever finds it, to be forwarded to Hatch. Working with Hatch, he is then able to draw a cable into his cell, along which any small item can be smuggled into the building. One of Augustus's primary needs is for nitric acid, which he uses to cut through the cell's window's bars. Along the way, he tosses out impossible fillips and red herrings, such as writing notes with no pen and making change from a five-dollar bill. He also indirectly manages to get an inmate to confess to a crime he committed, something the detectives had been unable to accomplish. Everyone around Augustus is amazed at his explanation, and they wholeheartedly believe his point that nothing is impossible, though the warden asks what would have happened if many of the key elements of Augustus's escape had not been present. Augustus smiles smugly and states that there were also two other ways out, and leaves it at that.
