The series follows Ye Wenjie, an astrophysicist who sees her father beaten to death during a struggle session in the Chinese Cultural Revolution, who is conscripted by the military.
While hanging out with Saul (Jovan Adepo), Will (Alex Sharp) collapses and is re-admitted to the hospital as his cancer worsens.
Wade (Liam Cunningham) introduces Jin (Jess Hong), Raj (Saamer Usmani) and other PDC members to the next phase in their plan; cryonic technology.
Given Will's imminent death from cancer, Wade suggests he fill the candidacy as the cryo-sleep brain (as physics expertise and minimal weight are necessitated) to be sent in the Staircase Project.
Ye Wenjie (Rosalind Chao) meets with Saul and attempts to pass on her knowledge about cosmic sociology in the form of a joke that the San-Ti will have difficulty deciphering, saying, "Don't play with God."
Realizing that Will bought her the star, Jin rushes to the hospital to change his mind, but arrives too late as the procedure has already started.
Ye Wenjie decides to go back to Inner Mongolia and returns to the Red Coast station, finding it destroyed.
"[5] Johnny Loftus of Decider wrote, "It’s terminal cancer patient Will Downing's time to shine in Episode 7 of 3 Body Problem, because his unique skill set – willing temperament, Oxford-trained smarts, eroding physical form – makes him the perfect candidate for Thomas Wade's Staircase Project.
Before this episode, he feels underdeveloped and lacks key components that make a compelling character, such as backstory, interests, hopes, dreams, and so forth.
