Leela struggles to understand the fundamentals of commerce during a shopping trip on a market world with the Doctor. Then, she spots a weapon that appeals to her. Paying the merchant, Jason, she examines her new toy. Soon, however, she is slain by Jason's knife. The Doctor discovers her dead body and demands answers. A local policeman explains that no laws have been transgressed; Leela has bought a legal death experience. Soon, she springs back to life. Jason explains that the knife's edge contained not only a fast acting poison, but also restorative microscopic robots. Whole again, Leela returns to the TARDIS with the Doctor, musing on the newfound appreciation she has for life now that she has died. The Doctor, having come back from the dead himself, can appreciate her point.
