The Enterprise welcomes two Iyaaran ambassadors, Loquel and Byleth, who are visiting the ship as part of a "cultural exchange" that will also send Picard to their planet. Before Picard departs, he assigns Troi to act as Loquel's liaison and asks Riker to do the same for Byleth. But Byleth has other ideas, and instead demands that Worf serve as his shipboard guide. Soon afterward, Picard departs for the Iyaaran home world with Voval, the Iyaaran shuttle pilot, who is gruff and uncommunicative. Their awkward silence is disrupted by a malfunction aboard their ship. Crashing on an unknown planet, Voval receives a concussion, but Picard is seemingly unhurt. He decides to seek help outside, but falls to the ground trying to traverse the planet's stormy surface. While he lies unconscious, someone silently drags him away.

Picard awakens on the distant planet in a small, dimly-lit cargo cabin. He is approached by a solemn, attractive human woman who informs him that Voval did not survive the crash. Picard learns that the woman's name is Anna and that she is the sole survivor of a Terellian cargo freighter crash that occurred seven years before. After Anna tells him that he has three broken ribs, he sends her to retrieve the shuttlecraft's com panel to send a distress signal, but she accidentally destroys the transmitter module while removing it. Picard is then shocked when Anna suddenly kisses him and tells him she loves him.

Back on the Enterprise, Troi has introduced Loquel to dessert, and Loquel is so intrigued that even the next morning he is drinking sweet juice. Worf has had about all he can take of his abrasive, demanding guest. Riker decides that the tension might be eased by a "friendly" game of poker. The game is anything but "friendly," and Worf realizes that Byleth is stealing chips. Before long, Worf loses control and, despite Riker's insistence that he calm down, attacks his guest. But instead of getting angry, Byleth is pleased. He expresses admiration for Worf's display of anger and politely excuses himself to document the experience, leaving everyone confused (with the exception of Loquel, who is still reveling in his dessert).
