About to, On the verge of

The noun ところ (sometimes shortened to とこ) is often used to describe the 'place' or 'situation' in which something happens. The primary determining factor for the nuance of ところ, is the tense of the verb it follows. When it is in the non-past form, ところ means 'about to (A)', or 'on the verge of (A)'.

Examples:

今から帰るところです
"I am just about to go home."
今から友達と会うところです
"I'm about to meet my friend."
