George Ball and Tom Watson are firemen who rescue 'Nugget' Joe McDermott from committing suicide by drowning.

The boys keep an eye on him and Joe is thankful for it after receiving a telegram the next morning from Rosette claiming that she still loves him.

They catch up to Joe on his boat for the Yukon and try to get him down to the police station only to see the ship depart San Francisco with all three of them on it.

Joe returns to Alaska, with George and Tom anxious to get him back to San Francisco to clear their names.

Jake is not happy about this turn of events and sends his gang to deal with George and Tom, who manage to outwit them.
