The Rangers now have their backs against the wall in the Stanley Cup Final and will have to win four straight to bring home the Cup.
The Blueshirts are in that hole after losing Game 3 at the Garden 3-0.
For inspiration, the Rangers only have to look to the other locker room to find a team that completed the rare comeback.
The Kings rallied from a three-game deficit against the Sharks in the first round of this year's playoffs.
Rangers players say they just have to take it one game at a time.
"I think both teams know it's possible to turn this around," said Rangers goalie Henrik Lundqvist. "They've done it, and we know we can do it. It's not like we've been outplayed here."
"We're not down on ourselves," said Rangers defenseman Dan Girardi. "We got a lot of work ahead of us, but like I said, just got to kind of mentally get prepared for tomorrow today and just have a great game tomorrow."
"We're facing the exact same situation we were against Pittsburgh. We lose, we're done," said Rangers head coach Alain Vigneault. "So if we don't want to be done, we got to win."
The Blueshirts could get a boost from suspended forward Dan Carcillo, who is eligible to return to the team for Game 4 Wednesday night.
