Looking for a 2–4 minute scene to rescore (character introduction montage)

I’m searching for a film or series scene (about 2–4 minutes long) that fits this specific structure for a rescoring project:

The main character is meeting with a broker or handler, discussing an upcoming mission or operation.

The broker says something like “we need another member” or “there’s someone you should meet.”

The scene then cuts to a montage of that new character in action during past missions or operations, while the broker narrates or describes them.

Finally, it cuts back to the present as that new character arrives at the meeting point.

Basically, I’m looking for a “character introduction” sequence that uses narration + montage + final reveal. Any suggestions from movies or TV shows that match this would be super helpful.
