Sr. Corporals Jason Perez and Rich Emberlin are called out at 3 a.m. to handle a tough case--the FBI is taking down an alleged heroin ring, and the suspects may have AK-47s. Later, Steve Claggett and the team run a warrant on a house that SWAT has already hit eight times, but the place is better fortified each time. And Jason recruits fellow officers to help build homes for displaced Hurricane Katrina victims.
