Hisashi Aoyama

Three sisters gather to celebrate their mother's birthday at a relaxing ryokan with onsen; each other's company seems far from the relaxation they are after. (Movie edit of the 5-episodes TV drama).

Takeshi Hongo is a promising young man with a passion for motorcycle racing. However, his dreams are suddenly ruined when he gets kidnapped by Shocker, the evil secret organization planning to dominate the world. After being remodeled into a cyborg, Takeshi escapes and swears to protect the world from the inhuman monsters.

The drama is a family story with a lot of black humor about the tragedy and joy of three sisters who gave their mother a trip to a hot spring for her birthday.
