edit Theme One Page

Cheers,
I downloaded the theme One Page, I edited part of its interface, menus and added a few widgets and plugings.
However, I still have not located the php file or page or post where I can edit the original text,
for example, just below the header and the menu appears an element called homepage_top_feature
which it contains a background image and a text in an area like this:
«A placito bene – You have just dined, and however scrupulously the slaughterhouse is concealed in the graceful distance of miles,
there is complicity. «Texts like these are those who wish to edit.

Please I need help to edit this and other texts predefined template
