Ace diver Shen Xingci lost his partner in an accident and has since been sealed in a coastal town, guarding an abandoned diving station. Even the sea breeze felt like a silent accusation. Until the mysterious researcher Lu Xun'an came to the door and asked him to lead a team into the submarine canyon to search for the legendary deep-sea ruins. Lu Xun'an's eyes had the same scars as Shen Xingci's. He spoke little but was thoughtful. He could always hand Shen Xingci a cup of warm ginger tea when she was on the verge of collapse. Diving again and again, brushing against danger again and again, Shen Xingci's dusty memories were peeled away layer by layer, and Lu Xun'an's purpose gradually emerged - what he was looking for was the truth about the accident that year. The undercurrent of the deep sea carries past regrets, but it also allows two lonely souls to find each other's salvation in the cold water.
Purpose: Reconcile with the pain of the past, and watch each other in the desperate situation of the deep sea
