After arguing with his sweetheart, Becky Thatcher, Tom Sawyer seeks solace from his friend Huck Finn, who tells him about a mysterious cure for warts that requires them to visit the localcemetery at midnight. While there they witness a murder committed by Injun Joe, who convinces Muff Potter, who also was there but in an inebriated state, that he is guilty of the crime. Tom and Huck promise each other they will not divulge what they have seen. When Tom is caught lying about stealing his half-brother Sid's crabapples, his Aunt Polly punishes him by making him whitewash the fence on a Saturday morning. The boy leads his friends to believe he is enjoying the task, and before long they are giving him their treasures in exchange for the privilege of joining in the fun. Together with Huck and Joe Harper, Tom runs away from home to become a pirate. The three set off on a raft to Jacksons Island in the Mississippi River, where they remain for three days. Upon returning home, Tom discovers it was thought the three had drowned, and the boys attend their own funeral service at the church. At Muff Potter's trial, Tom admits the truth about the murder, but Injun Joe manages to escape. While attending the school picnic near a cavern, Tom and Becky decide to explore it and get lost. As they try to find their way out, they stumble upon Injun Joe and a chest of gold. While angrily pursuing the two children, he falls into a crevasse and is killed. Huck finds Tom and Becky and leads them to safety, together with the treasure.
of The New York Times said of the film, "It is an extraordinarily faithful conception of the book, and while there are of necessity certain omissions and other parts that receive but scant attention, the main incidents are included in a detailed fashion. It is wonderfully interesting to see Mark Twain's characters come to the talking screen, for if there are minor discrepancies, they are unimportant... Jackie Coogan's Tom Sawyer is excellent... In fact, the whole cast is unusually competent. Mr. Cromwell's direction is imaginative and restrained. The result is that this picture is one of the few that can be seen with appreciation and enjoyment, even immediately after reading the book over again." However, this version was eventually superseded only eight years later by David O. Selznick's 1938 Technicolor remake of the novel, which, true to Selznick's legendary fastidiousness, boasted not only better performances but a far more cinematic style than the fixed-camera early talkie look of the original. The cave sequence in the 1938 version is noted for being one of the most terrifying sequences in a family motion picture, with Becky Thatcher toppling over into hysteria after the death of Injun Joe.
