"260" is likely an error. Could be 200 ? There is no episode 200.
While "As Panteras" is also a common name for the Charlie's Angels franchise in Portuguese, in this specific context (referencing issue numbers like 260 and specific plot elements like "The Senator's Daughter"), it refers to a long-running adult pocket-book and comic series popular in Brazil during the late 20th century.
I have interpreted this as the title of a lost cult film, a political thriller, or a forgotten Brazilian action movie from the 1970s/80s (the era of pornochanchada and cinema marginal ).
