Not sure you even need the first part. A character has a problem and tries to solve it, until he either succeeds or definitely fails. Lots of stories start with a conflict at the very first line, without any kind of setup (especially thrillers).

Well, most stories somehow try to establish who is the protagonist of what follows.

(1) stuff happens

You still need a resolution, though. (1) conflict (2) either conflict is solved or it is definitely unsolved.
