Clyde Beatty, an animal trainer and circus star, leads a search for his missing girlfriend and her father who were on an expedition looking for a lost tropical island. Using a dirigible as his mode of transportation, Beatty and his band head off in search of the missing explorers only to crash their airship on the same island their friends are located. Battling wild animals and a gang of greedy men searching for gold, Beatty and his party must rescue his girlfriend and father all the while trying to escape their jungle island. Feature version of the same-title serial of the same year, with refilmed sequences substantially altering the plot and characters of the original chapterplay.
