Indiana Joan (Porsche Lynn), back for another adventure, is in the middle of getting desk-banged by Rick Savage when she's beamed up by a passing space ship (huh?) -- for more sex. Then David Morris tells Melissa Murray, that Indiana needs him to go on a treasure hunt whereupon he starts groping for Murray's lost grail. So far, the sex scenes are coming as frequent and non-stop as UHF-TV movie commercials. Then, bingo, Morris and Lynn are in Egypt (presumably), and drop into a temple -- literally -- where everyone dresses like Phyllis Diller.  Captured, Lynn sucks her way to escape through a bunch of Eddie Murphy-clone temple guards. Lynn evidently needed the money to do this one; make it Joan's last crusade. Nice packaging.
