Ten years later, Ushio is a financially stable sleazebag. He works for an at-home health (read as: prostitution) company. One day he receives an invitation from a mystery novelist to a party on a private island celebrating the novelist’s career. (Despite being a one-hit wonder, Ushio is still known to the world as an author.) Ushio brushes off the invitation until he discovers one of the girls at his company moonlights as a mystery writer—and also received an invitation.
The pair and three other mystery novelists set out for the island, which contains nothing but the host's mansion and studio. However, when they arrive, their host is nowhere to be found, and five dolls have been set up in the dining room. With five four mystery writers (and one sleazebag) present, it doesn’t take them long to figure out what the dolls mean. The group is essentially stranded on the island (their boat lost some fuel on the ride over and doesn’t have enough for the return trip), so they resolve to take precautionary measures that night and figure out what to do tomorrow—which is not cautious enough, since someone massacres all five overnight.
