Waldo convinces Duncan to leave everything to David in a scheme to get the money with the help of nurse Jane Chase, who loves David. Waldo plans to frame David for Duncan's murder and manipulates the situation to carry out his plan. After John asks David to end his suffering, Waldo decides to kill John himself. Waldo gives David a poor defense during his trial and David receives a life sentence. Waldo forges a suicide note from John to secure David's release, but plans to kill him himself.

David is saved by the police, and Waldo dies realizing he cannot manipulate people like pawns.
