Synopsis by Hal Erickson
At 50 minutes, Call of the South Seas must qualify as the shortest of Republic's non-western B films. Janet Martin plays Tahia, princess of a faraway tropical island. Tahia's people are being victimized by extradition-free crooks led by an unsavory type named Landrau (Roy Barcroft). Disguised as a scruffy beahcomber, FBI agent Kendall Gaige (Allan Lane) infiltrates Landrau's gang, and along the way finds time for romance with Tahia. A climactic motorboat chase during a volcanic eruption, staged by the legendary Lydecker brothers, provided stock footage aplenty for future Republic programmers.
