Yotsuya and Ichinose are enjoying a hot afternoon when they recall the time that the tenants of Ikkoku-kan and Mitaka go off on a cruise to party hard aboard Mitaka's new boat; however, the boat falls apart, and everyone is shipwrecked on a deserted island. With everyone up to their usual antics and shenanigans, what can happen in such a desolate place?

In the town of Clock Hill, there is an old boarding house called Maison Ikkoku. While the residence itself is fairly normal, most of its occupants are not. Yuusaku Godai, its most quiet tenant, has finally reached his limit with his neighbors' constant disruptions and boisterous partying. Wanting a calmer place to call home so that he can study in peace, he prepares to move away. However, his plans to leave are suddenly interrupted when he meets the new boarding house manager, Kyoko Otonashi. Falling madly in love with her, he decides that the boarding house may not be such a bad place to live after all. Unfortunately for him, Kyoko has her own romantic troubles: she is a widow whose husband died six months into their marriage. And despite her blossoming feelings for Godai, Kyoko still cherishes her dearly departed husband, and she believes that no other man could possibly fill the void in her heart. But with Godai's persistence and some help of the other eccentric tenants, she may experience true love once again.

The Maison Ikkoku tennants throw a party to celebrate the marriage of Yuusaku and Kyouko. However, during the party Yuusaku hears that Kyouko is waiting for a letter. He becomes jealous and begins to doubt Kyouko, worrying that she still loves someone else. When the morning arrives, the answer to his worries is revealed... (Source: AniDB)
