Bear and Eric must haul a boiler and a flare stack--two critical pieces of equipment--to Langley at the same time that a polar bear is spotted in the area.

Rick is irate about a 5-day-long trip that his bosses assign him, and his frustration mounts along with his threats to quit. Alex's health continues to deteriorate and he must be med-evaced to the Yellowknife hospital, his fate unknown.
