Haruka Nanase nears graduation from Iwatobi High School as four short stories follow the swim club's last months together. Haruka and Makoto Tachibana hunt for a Tokyo apartment near a pool, the Iwatobi and Samezuka teams plan a send-off for Rin Matsuoka before he leaves for Australia, and Rei, Nagisa and Gou shoot a recruitment video for new members. A compilation film of all-new episodic stories continuing after the previous Free! films, not a new season.
