Johnny Hines, a popular light leading man of the early 20s, starts as Burn 'Em Up Barnes -- even his parents call him Burn 'Em Up', so I suppose odd baptismal names were popular back then -- in this racing car comedy, a popular genre of the era (Wallace Reid starred in a series of them for Paramount). The script is fast and furious until the plot kicks in, with funny titles and sight gags galore.
