Fireballs (1989)

In Northern Ontario, a fire hall is invested with disgusting creatures called -- firemen. When a Japanese businessman Mr. Matsuro wants to build a factory in the town and it just so happens that he has his eyes on the old fire station. And when discovering how much the firemen are a discrace they're order to hire some new recruits, and that's when they get the idea of a bikini contest where they hire four beautful women. Once again the Mayor finds out and puts a stop to it and replaces them with Mr. Matsuro's selection of new Japanese recruits. One problem though, the Japs are heavier partiers than our heros, so when a real fire breaks out, it might be up to the laid off losers to save the day.
