When the Timberwolves get a new coach, they also get the coach's son. The only problem is that Eldridge Elwell is a terrible hockey player. The team is on the hunt to make the playoffs, and every time Eldridge plays a shift, it hurts the team more. Johnny Maverick is just as angry about it as anyone on the team, until he learns something important about the coach's son.
There's plenty of action both on and off the ice. At a big tournament in Calgary, teammate Tom Morgan plays a practical joke on Johnny Maverick, so naturally Johnny feels he has to pay him back. The rivalry escalates. After he scores a hat trick, Johnny is given a hockey stick signed by all the members of the Calgary Flames. He worries that Tom will do something to this prized trophy and decides he will not let it out of his sight. But in the end Tom outsmarts him one more time and Johnny learns that revenge is never a good idea.
The Howling Timberwolves need to win the best two out of three hockey games to make it to the championship finals. But first Johnny Maverick has to survive a visit from his six-year-old cousin, Sarah. And not even Johnny's dog Marvin is safe. Worse, Johnny's got a big lesson to learn on the ice, too. As always, Johnny and Stu and Tom thing they have the answers. But, as usual, they are wrong.
