In 2047, brain-computer consciousness access technology became popular, and the Tidal Virtual Town became a temporary refuge for terminally ill patients.
Shen Qitong has been paralyzed for eight years and is physically trapped in the ward. He can only run freely on the beach with 72-hour continuous access rights. In order to study special neurological cases, surgeon Jiang Yubai stepped into the town as an observer. He only recorded data, but was accidentally moved by the young man watching the sea barefoot.
A trapped and broken body has a short virtual respite; a person holds a complete life in his hands, but is suffocating step by step in reality.
From the estranged confrontation between the researcher and the test subject, to the heart-to-heart talk on the rainy day when the tide suppresses the sunset embankment; from concealing their inner weaknesses to facing the reality of family relationships and life and death choices.
Renewal time limit, permanent residence of consciousness, guardian renewal, virtual immortality where memory will slowly wear out... They are repeatedly pulled between the virtual waves and the shackles of reality.
When permanent residence equals physical death, Jiang Yu gives up all ties between the scalpel and reality and embarks on the same path as Shen Xitong.
The tides go back and forth, the memories will eventually be mottled, and the cares of the world look at each other from a distance through the looking glass.
But there are always two people on the Sunset Causeway, and a sea that never stops.
Purpose: to explore the pros and cons of immortality in the near future, and to explore the belonging of sex and spirit; to tell about the two-way redemption of love in difficult situations, to explain that love does not drag each other down, but to be willing to run on the same path; to reflect on life and death, family affection and obsession, even if the memory will eventually wear away, the current bond has eternal significance.
