[2][3] Jerry Morgan is a ventriloquist who is having trouble with love: just when his relationship with a woman gets around to marriage, his dummy turns jealous and spoils everything.

In his escape, he finds himself impersonating a British car salesman, trying to demonstrate a new convertible with loads of bells and whistles.
