Nine is attracted by rules-smashing John at Princeton, but marries conventional Tom to escape from her family. Years later she meets John again when he is working for the Communist party, persuades him to run away with her to Europe. They take her hard-drinking grandfather with them and his death in Paris sends Nina back to the States, while John goes on to a little Spanish island where he finds peace and an answer to his questioning. Nina comes there, doesn't fit in, but finally through an heroic act is accepted....Then the Spanish War touches them and they decide to stay with their island rather than escape while they can. Rootless and unstable young people finding something to believe in and hold to. Has some nice moments but is not very important.
