Deep Sea tells the story of a girl who stayed in the house after her parents divorced and her father remarried and had children, and her personality became withdrawn and gloomy. She curled up in her red sweater all day and suffered mental torture day after day. She is eager for the attention and care of her family, but her divorced parents are busy with work and have no time to pay attention to her "small emotions".

Even her birthday was completely forgotten by her parents, and the only birthday wishes she received were from the merchants. Her father asked her to sit down and raise a glass just to celebrate her brother's kindergarten. She doesn't even remember that today is her birthday.

Deep down, Betelgeuse has been eager to find her mother. She was so happy when she was a child. Now, my mother is gone, leaving her alone in endless darkness, lonely and desperate. However, she never imagined that a cruise ship trip inadvertently rewritten her life.

Film evaluation of Deep Sea:

The whole movie presents a dazzling animation tone. Deep sea is a warm dream, so it must be different from the gloomy sea and family life in the real situation of this movie. Red, orange, yellow, green, blue and purple, whether it is fish and jellyfish in the deep sea, furnishings and figures in deep-sea hotels, or undercurrents and eddies of scrolls, are all endowed with extremely complex colors.

In most cases, these pictures are not quiet, but dissipate or gather, rise or sink, cycle or stop, and "drift" regularly or irregularly, which constitutes a "meaningful form" that is very suitable for dreams.
