Circus performers Chuck Reardon and Hubert "Fearless"
Frazier flee an African town when their human cannonball act
accidentally causes the circus to burn down. After diamond
mine owner Charles Kimble saves them from arrest in another town,
Chuck, always on the lookout for instant wealth, purchases a diamond
mine from him. Chuck and Fearless realize that they have been
duped when they learn that Kimble is an eccentric whose signature on
any document is worthless.
Fearless, who has been Chuck's "human cannonball" for
longer than he likes, is furious that Chuck has spent the $5,000
that took them five years to save on a worthless mine deed and sells
the paper to a shady character named Lebec. When Lebec and his
thug come after them for directions to the mine, Fearless and Chuck
take a boat and escape with the money.
In an unfamiliar town, they are conned into buying
beautiful Donna Latour out of apparent slavery by her partner, Julia
Quimby, who is working with the slaver to split the proceeds.
Donna then suckers Chuck into a safari with a sob story about
finding her ailing father in the jungle. In reality, she just
needs help crossing Africa to reunite with her wealthy fiancée.
Fearless is suspicious of the women, but he and Chuck
nonetheless pay for the safari. Along the way, Donna flirts
with both men and plays them against each other, but sincerely falls
in love with Chuck. Chuck and Fearless finally find out they
have been duped and leave the women to continue on the safari, but
then get lost themselves without their African guides.
Chuck and Fearless are trapped by cannibals when they
stumble on a sacred cave. When the cannibals pit Fearless
against a gorilla in a wrestling match to determine if Fearless is a
god, Fearless loses the match, and the two men are fattened up for
days in preparation for dinner. Just as they are about to be
dunked into a giant kettle, Fearless and Chuck outwit the cannibals
with a game of "patty cake" and flee.
In an African town, Chuck promises to buy steamer
tickets for home but instead returns to the apartment with Donna,
whose fiancée rejected her, and Julia. Chuck and Donna reunite
and the four friends form a new carnival act.
