Narrative:
The denver 9 controller had two aircraft (aircraft X and aircraft Y) on converging courses at the same altitude (FL370). If the D side from ZMP sector 42 wouldn't have the called denver 9 controller to turn aircraft X 20 left; separation would have been lost less than 5 miles inside of our airspace. Both aircraft were less than 2 minutes from the boundary when we initiated the call to ZDV. With the 20 degree left turn; the aircraft passed approximately 6 mile from each other at the same altitude and within 5 miles inside our boundary! Unbelievable!
