The factual background of the intimate close up picture of the hordes of '49ers crossing the ""great American desert"" and the mountains to find fortunes in the Far West, is based on factual records, diaries, etc. The story told against this background is that of a girl whose father had made all the preparations before his death and who determined to carry on. The picture is not a pretty one. Sharp play, plotting, gangster tactics '49 variety, have their part, in a closely knit story of the long trek. There is enough romance interwoven to interest girls.
