The crew of the
Duncan yacht belonging to Lord Glenarvan, catches a shark in the waters of
Scotland. When cutting the carcass, a bottle is found inside the fish, in which a request for assistance is written in three languages from a victim of a shipwreck. The documents have been strongly spoiled by water, however they manage to decipher that Captain Grant's ship has crashed on the
37th degree south latitude. It is not possible to determine the longitude of the crash site. Glenarvan goes to
London to organize a rescue mission, but the government denies him, citing the vagueness and inadequacy of information. The implicit cause of the rejection was Captain Grant being a Scottish patriot who dreamed of independence for Scotland. Moreover, the main purpose of his voyage was to establish
Nova Scotia. During the absence of the Lord, Captain Grant's children, son and daughter came to the boat in the hope to learn something about their father. When Glenarvan returns home, his wife persuades him to go in search of the captain on the
Duncan. The travelers move by land and sea, cross
Patagonia by the 37th parallel, visit the islands of
Tristan da Cunha, and
Amsterdam, pass by the south-eastern
Australia and
New Zealand. Having experienced many dangerous adventures, they find Captain Grant on the small island of
Tabor, which is also located at the 37° south latitude. ==Cast==
