某年夏天，六年级小学生裕太（武井证 配音）独自来到位于深山的萤之丘水库。当年他曾和父亲来到这里捉独角仙，一年前父亲意外去世，曾留下无数美好回忆的水库，对他来说自然别有一番意义。在此期间，他遭遇罕见的暴雨，结果不小心跌落水库。幸运的是裕太成功获救，在一个古色古香的小村庄里，他结识了可爱天真的小女孩纱荣子（木村彩由实 配音）。偶然间裕太发现，自己正身处昭和25年（1950），而这里正是后来沉入水库的小村庄。意外穿越时空三十年，对裕太来说究竟意味着什么呢？ 本片根据网络作家川口雅幸的同名原作改编。
In this season, the show went back to airing one new episode a week, but stayed in the hour-length format, filling up the second half-hour with episodes from previous seasons and some of the prime-time specials from the 1980s. This entire season, along with the second half of season 6, is available on Garfield and Friends: Volume 5 DVD set. Also worth noting is that here, a new theme song was added that was written by J.R. Johnston and Neil Panton. The theme was sung by J.R. Johnston. This theme song was not shown internationally, and as a result, it does not appear on the DVDs (although Garfield's quotations are kept intact). This new introduction sequence used most clips from Seasons 5-7 and a few from the first two seasons, as well as Garfield in Paradise and Garfield's Feline Fantasies. The episodes stopped using a few seconds of the theme playing in the episode title cards after season seven's fourth episode; music from the episodes were used in the title cards until the show ended, even though season six used music from some of their episodes.
The truths and half-truths about Dr. Venture's former arch nemeses are finally revealed.
