Edna's father greedily wants her to marry wealthy Count Chloride de Lime whom neither she nor he has ever met.
Edna drops a note to her Charlie explaining her plight and asking him be her knight and save her.
However, the true Count de Lime arrives and Charlie is roughly escorted away as an impostor.
An automobile chase featuring Edna and Charlie in one car (a two-seater roadster) and the pursuers in another (a four-seater) ends with a few timely and accurate brick tosses by Charlie and the pursuing vehicle being bumped off a pier.
When she throws a note out of her window to Charlie, it is signed Iona Lott (I own a lot).
