In the first part of this special one-hour season and series finale, Dharma and Greg find themselves once again trying to make peace between their polar opposite parents when an argument breaks out over whether the couple will vacation with the Finkelsteins or the Montgomerys. Dharma tries to appease both sides by arranging for everyone to spend the weekend at the Montgomerys' mountain chalet, but when the usual bickering and insults kick into high gear, it finally sends Dharma and Greg over the edge. Meanwhile, back at the office, Pete is left in charge of a routine SEC inspection, but when the agent turns out to be beautiful and female, he invents wild stories about inside trading... oh, just fast forward. (Part 1 of 2)

Dharma & Greg get stuck in a snowstorm after leaving the chalet and begin to wonder how their diverse upbringings will affect them as parents. (Part 2 of 2)
