. Dr. Crusher consults a specialist, Dr. Russell, who suggests a risky, possibly life-threatening, experimental, untested procedure that may allow Worf to regain all of his mobility; essentially, they clone his spine, extract the original and replace it with the new one.

 recommends implants that transmit neural signals which would allow him to regain about 60% of his mobility. However, Worf does not like the idea of being an injured warrior nor "lurching through corridors" so he considers his life to be over.

Dr. Russell volunteers to assist in treating injured colonists whose transport had struck a mine. Crusher finds that she has used an experimental drug on a patient that subsequently died, and quietly but strongly reprimands Russell for not using proven methods first.

and Alexander of his demise, but minutes later they are pleasantly surprised as Worf revives due to the redundancies built into his body that back up even his neural functions.

Later Dr. Russell enters Dr. Crusher's office, and Crusher tells her that while she is delighted that Worf will recover, she is horrified by Russell's immoral methods of putting her own interests in collecting research data and gaining recognition for herself above patients' interests and lives. Russell silently leaves the room.

Back in his quarters, Worf relearns to walk, and accepts help from Alexander in mastering the use of his legs once again.
