The Lone Defender (1930)

The Lone Defender is a 1930 American Pre-Code Mascot serial film starring Rin Tin Tin. It was Mascot's first all-sound serial (the second to have any sound at all, after the partial sound in The King of the Kongo). It was Rin Tin Tin's first serial at Mascot, after being dropped by Warner Bros. when they decided animal pictures would not work with "Talkies". He also starred in the later serial The Lightning Warrior, which was his last appearance (he died in 1932). The plot revolves around Rin Tin Tin as "Rinty" and a secret gold mine fought over by the criminal "The Cactus Kid" and the legitimate owners. Material from this serial was edited into a feature film version and released under the same name in 1934.
