SOS is universally recognized as a distress signal, and it has been ironically well-used to title this unfortunate tape.
Leaving aside the tracking problems which may be specific to the screener AVN received, S.O.S. 2 looks like raw footage Scotch-taped together with camera moves and directions to both performers and tech crew left in. The director has more lines than anybody on the screen, and his hand even makes an inadvertent cameo appearance when he illustrates the instruction "Turn around like this."
Four b/g scenes and one g/g.
A pretty-good 75-minute wall-to-waller could have been made from this footage, but this isn't it.
