The Enterprise hosts two Iyaaran ambassadors as part of a cultural exchange: one is assigned to Troi and the other seeks to provoke an undiplomatic Worf. Meanwhile, Picard crashes on a barren planet en route to Iyar and is rescued by a woman who falls desperately in love with him.

• Loquel was using Worf to study antagonism (with some amusing results). Byleth was using Troi to study pleasure (no, not that kind!). Voval was using Picard to study love.
  
• Troi's favorite desert is Ktarian chocoloate puff, made of 17 varieties of chocolate.
