While Captain Maxwell Peters leads a typical scouting and charting mission, a rash of murders and sabotage forces him to search his own crew to find the traitor. He is determined to find out who committed these murders, while meanwhile a saboteur has crippled the ship, and the murderer is now stalking his the next victim.
Now a desperate plan is prepared that will draw the murderer out into the open once and for all, or doom them all to drift in space until they run out of supplies. Captain Peter's tension-filled and suspense-filled investigation builds to a can't-stop-now, page-turning, action-filled climax.
