John takes Kwan to an old friend and learns more about the mystery object which the Covenant is determined to steal. With the alien threat growing, Dr Halsey has a plan to deal with John's unpredictable behaviour.

John meets his new 'partner' and discovers secrets in his own memory. Kwan wants to continue her people's fight for independence, but Soren has different plans for her. Makee's plan to retrieve the Madrigal object has deadly consequences.

Guided by his visions, John takes Halsey and Cortana back to where it all began, looking for answers from his past. With Soren along for protection, Kwan goes in search of an army.
