One day in summer. Four men check into a resort hotel. Osamu (Mashima) is a writer whose debut work became a bestseller, but he hasn't been able to produce any hits since then. Suzuro (Yoshida) is a popular actor who came on a trip incognito. Kinichi (Seto) is an office worker who is stressed out at work. And Jin (Mori), who seems to know Megumi (Kakei), a hotel staff member, creates a mysterious atmosphere. They arrive at a summer resort, but each of them has a big problem. Osamu came to the office to finish his new work, but he couldn't concentrate and ended up feeling like he was on vacation...

Meanwhile, in another room, Kato is being held captive and is being held at gunpoint by a masked man.
