A Man Called Dagger centers on secret agents Dick Dagger and Harper Davis, who are on the trail of former SS Colonel Rudolph Koffman, who’s using a meat-packing plant as his secret lair. Koffman’s mistress Ingrid runs a beauty spa. One of her massage therapists, named Joy, reveals to Dagger that another employee named Erica, is being held captive at Koffman’s lair.

After being brainwashed, Erica makes a failed attempt to kill Dagger. Realizing his murderous plan has failed, Koffman kidnaps Harper, forcing Dagger to stage a daring rescue operation, during which he is also captured and then tortured. Dagger ultimately escapes and foils Koffman’s plot.

Directed by Richard Rush, A Man Called Dagger stars Terry Moore, Jan Murray, Sue Ane Langdon, Paul Mantee, Eileen O’Neill, Maureen Arthur, Leonard Stone and Richard Kiel.
