Though already established as Roy Rogers' favorite leading lady (offscreen and on), Dale Evans was permitted a rare non-western appearance minus Rogers in the 1947 Republic mystery thrillerThe Trespasser. Evans is cast as nightclub singer Linda Coleman, the sister of newspaper-book reviewer Bruce Coleman (William Bakewell). Bruce is engaged in a clever fraud, peddling rare-book forgeries to collector/publisher Channing Bliss (Francis Pierlot). This bunco scheme is uncovered by aspiring girl reporter Stevie Carson (Janet Martin), with the grudging help of veteran newshound Danny Butler (Warren Douglas). With all this going on, ostensible star Dale Evans has little to do except sing one sultry musical number and look smashing in low-cut gowns -- and, oh yes, indulge in a bit of romance with Stevie's editor Bill Monroe (Douglas Fowley).
