In this third remake of legendary Japanese director Akira Kurosawa’s hugely influential The Seven Samurai, the seven gunslingers (George Kennedy, Michael Ansara, Joe Don Baker, Bernie Casey, Monte Markham, Fernando Rey and Reni Santoni) liberate Mexican political prisoners, train them as fighters and assist them in a desperate attack on a Mexican fortress in an attempt to free a revolutionary leader.

Burglar Nat Harbin (Dan Duryea) and his two associates set their sights on wealthy spiritualist Sister Sarah, who has inherited a fortune — including a renowned emerald necklace — from a Philadelphia financier. Using Nat’s female ward, Gladden (Jayne Mansfield), to pose as an admirer and case the mansion where the woman lives, they set up a perfect break-in. Things get complicated afterwards.

A frustrated pianist himself, music journalist Myles Clarkson is thrilled to interview virtuoso Duncan Ely. Duncan, however, is terminally ill and not much interested in Myles until noticing that Myles’ hands are ideally suited for piano. Suddenly, he can’t get enough of his new friend, and Myles’ wife, Paula, becomes suspicious of Duncan’s intentions. Her suspicions grow when Duncan dies and Myles mysteriously becomes a virtuoso overnight.
