Lahela is determined to solve professional and personal mysteries. An athletic young man named Caleb, who is visiting Hawaii to hike the famed Stairway to Heaven, has lost all feeling in his legs for no apparent reason, and tests results are inconclusive. While Lahela is over the moon after sharing a first kiss with Walter, she's unsure of his true feelings. Lahela applies the scientific method to solve both enigmas and ultimately discovers that matters of the heart can't be explained by logic.
