Over shots of the Falklands Islands Dependencies, a narrator asserts that the territory has been in undisputed possession of Britain since 1907. Recently, however, the area has been disturbed by the appearance of representatives of rival states.

The annual re-supply of a British station in the Falklands Islands Dependencies. A map pinpoints the Falkland Islands and Dependencies. The narrator explains that the Falkland Islands were colonised by Britain over one hundred years ago, that the area of the Falkland Island Dependencies has been used for summer whaling bases by the British since 1907 and has been in permanent occupation since 1943, and contends that by these activities Britain has established legal sovereignty.

Reference is made to Shackleton's heroic journey to South Georgia after the loss of the Endurance in 1916.

The staff of Laurie Island Met Station go about their duties. The station is re-supplied by ship. The narrator points out that the eight British Met Stations in the Falklands Islands Dependencies satisfy a second requirement in international law for claiming sovereignty over unoccupied land: the nation claiming sovereignty must demonstrate it has undertaken some constructive action.

A derelict whaling station at Deception Island. The station was destroyed by the British during the Second World War to prevent its use by the Germans but, the narrator reports, it will probably be re-established shortly. Reference is made to a claim by the Chilean president that the area is potentially a source of great wealth. The claim is dismissed, and it is asserted that the land has so far yielded only trace minerals and low-grade coal.

Sea-Elephants bask on the shoreline at Admiralty Bay.

Bransfield House at Fort Lockroy is visited by Miles Clifford, Governor and Commander-in-Chief of the Falkland Islands and the Dependencies.

At Hope Bay, one of Britain's largest stations in the territory, the volunteer staff, each specialists in a different field, pursue various activities including the mapping of unexplored areas and the taking of meteorological measurements. The base is visited by a U.S. expedition led by Commander Finn Ronne.

The importance of Marguerite Bay, which commands the inland route to South Graham Land, is noted. Huskies used by the survey parties are trained at the station.

Over a shot of a sign reading 'BRITISH CROWN LAND', the narrator reaffirms that British sovereignty over the territory has been secured by long-term occupation and constructive work.
