When Una Chin-Riley and Christopher Pike meet at Starfleet Academy after one of his lectures, they immediately become friends. A stellar student, Una is the 'poster girl' of her class, and Pike is determined to become a Starfleet captain with his own ship, rhetorically assembling his dream crew. As their friendship evolves, Pike also suspects Una is involved with the Euxhana, a Chionian cultural minority, who are seeking asylum in Federation space, leading to more questions than answers. Twenty-five years later, Una and Pike are working together on the USS Enterprise to settle a Chionian trade agreement when a pro-Euxhana saboteur launches a terrorist attack. When the suspect is taken into custody for interrogation and is discovered to have a history with Una, her past associations resurface, threatening to expose a secret she's been harboring all these years.
