Due to declining libido and a falling birth rate, human civilization faces the threat of extinction. A sinister and unhinged mad scientist (played by Shaozhu) develops a mysterious formula intended to plunge all of humanity into obsession with pleasure.
Hearing of his scheme, the Injuu Sentai (Beast Squad) sets out to stop him. However, the Blue Warrior (played by Xiao Tie) is captured during the mission and subjected to ****** interrogation. In order to rescue their comrade, the team leader (played by Leo) and the Black Warrior (played by Koji) willingly take the “Aphrodisiac Pill.” As their long-suppressed desires awaken, they find themselves in a chaotic world where only overwhelming pleasure seems to hold any truth.
