### Story
Ogami Itto, the former executioner for the shogunate who now travels as an assassin-for-hire pushing his young son Daigoro in an armed baby cart, accepts a commission from the Awa domain. The domain's secret indigo-dye technique is at stake, and the job is to assassinate the clan traitor, dye master Tadazaemon Makuya, who is protected by the three brothers of the official escort service, Benma, Tenma, and Kuruma Hidari, known as the Gods of Death.[2](https://jfdb.jp/title/7723) • [7](https://subsnavi.jp/vod/lone-wolf-and-cub-baby-cart-at-the-river-styx/) • [12](https://www.hulu.com/movie/lone-wolf-and-cub-baby-cart-at-the-river-styx-defbee69-431e-443c-958f-e78a30ab0765)
Meanwhile the Shadow Yagyu clan, the force behind Itto's original framing and dismissal, continues its pursuit. Sayaka Yagyu (Kayo Matsuo), the female head of the Akashi Yagyu, sends against him the Besshiki onna, cold-blooded women martial artists who attack in disguise, as festival lion dancers, radish-selling girls, and commoners, with blades hidden in straw hats and riverbeds.[2](https://jfdb.jp/title/7723) • [1](https://eiga.com/movie/36523/) After a burning escort ship, Itto, Daigoro, and Sayaka escape together, and the film ends with the promised duel against the three brothers, who fight with hand claws, a staff-like weapon, and iron fists, on the sand dunes.[2](https://jfdb.jp/title/7723) • [4](https://www.nfaj.go.jp/program/misumi-2016-1-46/)
## Production and place in the series
The film adapts *Lone Wolf and Cub* (子連れ狼), the manga serial running in *Manga Action* by writer Kazuo Koike and artist Goseki Kojima, with a screenplay by Koike himself. Kenji Misumi returned as director and Chikashi Makiura as cinematographer from the first film, *Sword of Vengeance* ([子連れ狼 子を貸し腕貸しつかまつる](https://www.edgepedia.org/lone-wolf-and-cub-sword-of-vengeance)), and the film was produced by Katsu Production, the company of actor Shintaro Katsu, with Hisaharu Matsubara co-producing.[1](https://eiga.com/movie/36523/) • [3](https://www.criterion.com/films/28723-lone-wolf-and-cub-baby-cart-at-the-river-styx) • [4](https://www.nfaj.go.jp/program/misumi-2016-1-46/)
Japanese databases disagree on its ordinal position: JFDB, citing official Toho materials, calls it the third work of the film series, while eiga.com calls it the second film adaptation.[2](https://jfdb.jp/title/7723) • [1](https://eiga.com/movie/36523/) It reached theaters only months after the first film, and reviewers noted the speed of its production.[5](https://www.kinenote.com/sp/public/cinema/detail.aspx?cinema_id=19709)
## Style and action
**Escalated violence and gadgetry.** Compared with the first film, the baby cart is far more heavily weaponized and the splatter content increases sharply: blades spring from the cart's wheel axles to cut down ninjas at the ankle, blowguns are mounted on its sides, and severed limbs and fountains of blood recur throughout.[4](https://www.nfaj.go.jp/program/misumi-2016-1-46/) • [8](https://filmarks.com/movies/13206/reviews/190065737) The National Film Archive of Japan describes the film's acrobatic combat against ninja groups as varying its tricks scene by scene.[4](https://www.nfaj.go.jp/program/misumi-2016-1-46/)
**Fast cutting.** A statistical study of Japanese widescreen cinema found that this film was shot with an average shot length (ASL) of 5 seconds, among the fastest of the hit films of 1965 to 1972; the same study notes that Misumi, who had shot *Zatoichi's Flashing Sword* (1964) at an ASL of 16 seconds, cut far more rapidly here, an example of the series' own editing rhythm overriding a director's personal style.[9](https://www.jstage.jst.go.jp/article/jscsj/6/0/6_20/_pdf/-char/ja)
A Kinema Junpo critic observed that the film is carried by sound and violence rather than dialogue: Daigoro, a toddler, can only say "chan," and it is the attackers who talk, explain themselves, and drive the story forward.[5](https://www.kinenote.com/sp/public/cinema/detail.aspx?cinema_id=19709)
## Reception and legacy
The film has remained widely available in the West through the Criterion Collection's box set of the six Wakayama films, where it is presented as an exploitation-cinema classic that took the series' action and graphic violence to delirious new heights.[3](https://www.criterion.com/films/28723-lone-wolf-and-cub-baby-cart-at-the-river-styx) On Rotten Tomatoes it holds a 100% Tomatometer from 7 reviews and a 91% audience score.[6](https://www.rottentomatoes.com/m/lone_wolf_and_cub_baby_cart_at_the_river_styx) Scenes cut from this film form the bulk of *[Shogun Assassin](https://www.edgepedia.org/shogun-assassin)* (1980), the English-dubbed composite film through which many Western viewers first encountered the series.[10](https://www.eyeforfilm.co.uk/review/lone-wolf-and-cub-baby-cart-at-the-river-styx-1972-film-review-by-jennie-kermode)
In Japan the film is periodically televised and screened in Misumi retrospectives, including the National Film Archive of Japan's 2016 program and the Kyoto Historica International Film Festival in 2019.[4](https://www.nfaj.go.jp/program/misumi-2016-1-46/) • [11](https://historica-kyoto.com/2019/films/focus-2/2-2-3/) As of 2026 it is available for rental or purchase on Prime Video in Japan, with no flat-rate subscription streaming confirmed on major services.[7](https://subsnavi.jp/vod/lone-wolf-and-cub-baby-cart-at-the-river-styx/)
