A buoyant defensive effort from the Brisbane Broncos proved decisive for the visitors, who scored their first win in Melbourne in five seasons.
The hosts signaled their attacking intent early and spent a majority of the first half in the attacking twenty.
An in-form Blake Green drew first blood, scoring the first of two first half tries inside of eight minutes.
Storm continued to press the Broncos backline in search of a lead extending try, but the visitors were resilient in defense.

Despite the momentum being firmly in favour of the home side, the Broncos took a shock lead on the half hour mark in their lone attacking effort in a phenomenal twenty-five minute spell.
Although trailing, Storm refused to let up as captain Cameron Smith continued to lead a fast paced ruck.
Their attacking intentions were ultimately rewarded when Green crashed across the line for his second try of the game.
Both sides picked up where they left off in the second half, with Storm looking to capitalize on their dominance of possession in their attacking twenty.
In a replica of their first half try, the Broncos absorbed Storm's attacking pressure before rebounding to score against the run of play, this time through Anthony Milford who crossed in the left corner, giving the Broncos a slender 14-12 lead.
A series of passes from Will Chambers landed in the hands of Kurt Mann, who broke a tackle before diving across the line looking to help Melbourne regain the lead. However, some desperate defending from the Broncos left the referee to rule a strip in goal.
Storm continued to press for a match-winning try, forcing the Broncos to a record 11 goal line drop outs during the contest.
But it was ultimately the Broncos who went home with the two points, securing a narrow victory on the road.
