Dale Hunter poked home a rebound during a goal-mouth scramble 22 seconds into overtime, giving the Quebec Nordiques a 3-2 victory over the Montreal Canadiens in the fifth and final game of their National Hockey League playoff series tonight.

The victory sent the Nordiques into the quarterfinal round of the Stanley Cup playoffs against the Boston Bruins, starting Thursday in Boston. Quebec, winless in the Forum before the start of these playoffs, won two of the three games played here.

It was the second year in a row that Montreal has gone out of the playoffs in the first round. Edmonton eliminated the Canadiens last season.

Hunter's overtime winner came at the end of a two-on-one break as Hunter and Real Cloutier skated in on Montreal goaltender Rick Wamsley. Cloutier's shot went behind the net, where he retrieved it and scooped it in front to Hunter. Hunter pushed the puck toward the open side of the net. Wamsley got a leg on it, but the puck slithered over the goal line and, after a moment of confusion, the red light went on.

The Canadiens, who outshot Quebec, 35-19, trailed, 2-0, entering the third period, but forced the sudden-death overtime as Mario Tremblay beat Quebec goalie Dan Bouchard at 10:49 and defenseman Robert Picard's long, soft shot bounced off a player in front of Bouchard and went into the net at 12:14. Picard had scored only one goal in the regular season.

Wilf Paiement and Anton Stastny scored for the Nordiques in the first period.

Paiement scored after a three-on-two break with Stastny and Marc Tardif at 4:40.

Then Montreal's Doug Risebrough was penalized for high sticking, and it took the Paiement-Tardif-Stastny line just 24 seconds to capitalize again. Paiement knocked down Montreal defenseman Larry Robinson behind the net and, in the ensuing scramble, Tardif poked the puck in front to a wide-open Stastny, who pushed the puck through Wamsley's legs.
