Sarah grieves over his father’s death, the NSA dismantle the SSC and KITT’s AI chip is removed to be installed in his evil predecessor KARR, (voiced by Peter Cullen), who is being kept at Area 51. KITT secretly uploads his files to the internet to save himself, leading Billy and Zoe to try and piece him back.

Meanwhile, Sarah uncovers a windfall of funds secretly left by her father to restart The Foundation for Law and Government at the SSC, and Mike learns that he was the original operator of KARR but his memories of the events were erased. Mike infiltrates Area 51, installs KITT’s reconstructed AI into KITT’s body and the two have a final confrontation with KARR who seizes Torres as his new operator.
