A 42-second trailer with music and narration. It opens on an aerial view of the KILO compound, a figure-eight building on a tropical coastline, then tours the KILO pharmacy rooms. A faculty member in a white coat introduces the challenge, followed by a pediatric flavoring activity and a training-sample oral suspension. The habitat follows: the compound from above, a residential corridor, hydroponic gardens and residents at dinner. It returns to the coastline aerial and ends on the KILO logo with the text "Challenge 1 — Pediatric Patients. Accept the Challenge. RxCe.com."
