Persuaded by her father-in-law to give her negligent and drunken husband one more chance, Lucretia Eastman accompanies him on an expedition to the Arctic Circle, but Eastman turns back out of fear. Another ship, commanded by Frank Underwood, who loves Lucretia, arrives on the same mission, and she joins it. While Eastman denounces his wife and obtains a divorce, she and her lover are imprisoned for months in the icebound ship. After a trek across the frozen waste, they are rescued.
