Following the footsteps of many polar explorers, the small expedition
cruise ship 'Isis' heads south with a mixed group of passengers keen to
see Antarctica for themselves. After leaving Cape Horn behind they have
to cross the fearsome Drake Passage. This lives up to its reputation,
with the wind picking up and the ship sustaining what appears to be
minor damage during a storm. However the episode is soon forgotten when
the 'Isis' reaches the Antarctic and the passengers enjoy the
spectacular scenery and wildlife. Penguins, seals and whales are all
observed in glorious weather and a great feeling of contentment
permeates the ship. Things are going so well that the fateful decision
is taken to enter the Weddell Sea, the area where Sir Ernest
Shackleton's ship the 'Endurance' foundered in the ice. With modern
ice-strengthened ships and satellite technology such a fate nowadays is
unthinkable...
