Teams of 8: Tolle (X-IMP scoring).
(At least one contributor to this forum has already seen this hand with slightly different information, but these are the correct facts as I now understand them).
Game all, dealer W. E holds:
W opens 1 , playing Precision, so 5+ cards, <16 HCP.
N overcalls 2 and you elect to pass
S bids 2NT, alerted as a good 4-card raise to at least 3
W bids 3
N bids 3NT, alerted as a slam try (I believe without a shortage, but I have not been able to check this for certain)
S signs off in 4 , which comes back to you.
Do you take any action in the pass-out seat?
I'll reveal the nature of the misinformation in due course: the information given is the correct (and documented) statement of the pair's agreements.
