Plot: The Nirvana has finally reached its home solar system, but the Harvest fleet's remaining mother ships are not far behind. Despite this, the crew decides to hold a party to celebrate their coming home - that is, until they encounter their last obstacle to their home planets - a Tarak mobile mine field that threatens to destroy them all! With no desire to break through the field because it might slow down the Harvest fleet behind them, the crew of the Nirvana is left to guess the password to call off the system before it destroys them
