Crimewave (1985)

Synopsis
In a slapstick spoof of hitmen and crime stories, the head of a security systems company (Hamid Dana) is bumped off by two gonzo exterminators (Brion James and Paul L. Smith) who have gone from stomping out pesky varmints to stomping out human targets, and one of them does so with gusto. Now the exterminators go after the partner who hired them and his blatantly obnoxious wife (Louise Lasser) and in the meantime frame a poor security guard (Reed Birney) for the murder of the company boss. The tale is told in flashbacks, as the security guard has been tried and convicted and is shown at the beginning, about to be executed. ~ Eleanor Mannikka, All Movie Guide
