Can anyone explain the following wire set up?

At a single pole switch I have:

1 - 2 wire (black and white - probably the source)
1 - 3 wire (black, red and white - going to the ceiling box)

At the ceiling box I have:

1 - 2 wire (black and white)
1 - 3 wire (black, red and white - from single pole switch)

Where does the 2 wire at the ceiling box go to? What is it for?

This is why one should _always_ make a note what wire is connected
where, BEFORE they disconnect any wires.

Most likely one of the black and white pairs is the source, the other is
the feed for the outlets.

Do you have a test light (not a little neon thing, a 25w or bigger
LIGHT)? Test the black and white pair and both the switch and the
ceiling box. Find out which is the source.

Once you identify the source, my best guess is:
1) connect all whites together as neutral
2) connect all blacks together was "always hot"
2) connect the blacks to one side of the single-pole switch
3) use the red on the other switch pole as "switched power"

Verify before using that information.
