With less than half a day left in the Alaskan king crab season, the crews race the clock to get as much crab into the holding tanks as they can. Bad luck and mechanical malfunctions still plague some captains, who need to land a certain number of crabs just to cover their operating expenses, much less to turn a profit for the crew.As the midnight deadline marking the end of season closes in, the battle to unload begins. Boats are unloaded at the processing plants on a first-come, first-serve basis, and a couple of minutes can mean the difference between unloading immediately, or waiting in the harbor for days.

With one boat sunk and its crew missing, several Good Samaritan boats postpone their season to comb the frigid waters of the Bering Sea for survivors. The tragic news travels fast, but captains too far away to help with the search and rescue decide to concentrate on the baiting and setting of pots. As the remaining 170 boats in the fleet turn their attention to fishing, though, tragedy strikes again. A frantic call comes in over the radio from a boat whose deckhand has fallen overboard. The reality of another death strikes a nervous chord throughout the fleet and keeps everyone on edge as they continue to chase America's deadliest catch.

Less than a day into the Opilio crab season, the Bering Sea has already claimed six lives. Despite these losses, the rest of the fleet begins to pull the pots they set 12 hours before, their hopes high. As the weather turns for the better, fishing is made easier, and for the first time this season, there is a moment of calm on the Bering Sea.

Unseasonably warm weather and calm seas have contributed to three days of record catches for the fleet. It's not all smooth sailing for one boat, however, when an electrical fire breaks out in the engine room and its crew must scramble to fix the problem before safely returning to fishing. But as the fourth day of the season gets under way, the continued high number of crabs spurs rumors of an early closure, with every captain speculating on when the quota will be met.

Eighty-four hours into the Opilio season, the hunt for crab intensifies as rumors of a possible closure prompt the men to push even harder. Some boats are so successful their captains begin wondering where to put excess crab, while others, finally hitting the "honey hole", try to make up for their slow start. But throughout the fleet crews begin to fatigue as the pending season closure drives them forward. This is the last time they will fish in a derby-style competition, and everyone wants to make their final run a memorable one.

With the deaths of the Big Valley crew, this Opilio crab season has been a rough one. On every boat, crew members are reaching their limit, but are spurred on by the pressure to catch a year's wages in the next 24 hours. As the last hours of the season tick down, a new race begins: the race back to port. Since off-loading is done on a first-come-first-serve basis, captains must decide when and where to unload their catch, competing for the best spot in line at the processor. Crab can't last forever in a boat, so a few days waiting could mean tens of thousands of dollars.
