Suzumiya Haruhi no Yuuutsu (2009) EP10 孤島症候群・前編

A "distant relative" of Itsuki's allows the SOS Brigade, along with Kyon's sister, to stay at his newly built island villa. On their first day there, they enjoy the island's facilities, but are soon drawn inside by the arrival of a storm. While waiting for the storm to pass, Haruhi and her friends play games in doors and have fun together. Later, the owner of the villa disappears, and everyone starts searching for him. Ultimately, the SOS Brigade members find him dead in his room.
