It's night in Toronto, and Hope Zion Hospital's Chief Surgeon Charlie Harris is sitting in the back of a cab with his fiancee and fellow surgeon Alex Reid. Charlie wants to go around the block one more time, but Alex reminds him of their impending wedding - their guests are waiting for them at the hotel suite! Suddenly, the cab is rear-ended. Despite a good knock to the head, Charlie quickly emerges from the car to tend to the other driver, who has sustained a collapsed lung. Luckily, Alex has a pair of scissors and a tampon in her purse, which Charlie uses patch up the lung. With the initial shock of the crash over, Charlie feels pain in his head, then falls to his knees and passes out.
