Plymouth was a brand name owned by the Chrysler Corporation and began manufacture in Detroit in 1928.  Prices were slightly higher than comparable Fords but their first car, the Model Q, sold well.  Plymouth became one of the “Big Three” in US car sales and their vehicles were also manufactured in other countries.  After WW II, the company continued to prosper and their cars also had many successes in NASCAR events.  A wide variety of different Plymouth models were built over decades, before the name was discontinued by Chrysler in 2001.
