Colonel Ferris, a wealthy farmer in northern California, is strongly opposed to hydraulic mining, a new method developed during the gold rush of the 1870's, which is flooding the area's prosperous farmlands. Despite Ferris' political stance, Jared Whitney, a mining engineer from the East, becomes friends with the colonel's son Lance and falls in love with his daughter Serena. Family tensions deepen when the colonel's brother Ralph gives up farming to go to San Francisco to work for his wife Rosanna's father, Harrison McCooey, a leader in the mining venture. When Lance follows Ralph, the colonel, focusing his anger on Jared, forbids him to see Serena.
Also known as California Outpost, Old Los Angeles stars Bill Elliot in one of his expanded-budget Republic "specials." The film is set during the early statehood days of California, with Elliot keeping the peace and warding off plunderers and marauders. As always, Elliot is a "peaceable man"--until he beats the tar out of those who rile him. The problem with Elliot's more expensive Republic vehicles is that action invariably took a back seat to plot, romance, costumes and decor. Within a year of Old Los Angeles, Elliot started a more austere, less prettified and far superior western series.
