"Asian Heat 4" is a dull, repetitive all-sex video from Sin CIty Entertainment, in which Brooke Ashley hosts four vignettes, taking charge herself in the final one.
Studs involved are Rick O'Shea and Ian Daniels, while Umma, Tricia Yen and buxom Saki St. Jermaine fill out the femme cast. It's an extremely cheap production, with all scenes shot in the same bed, with some token decortions like fans posted on the bedroom wall.
For a tiny bit of variety, Umma and Tricia Yen contribute a lesbian scene with a dildo instead of the cocks provided.
This sort of filler had its place in Sin City's history, but I doubt whether it added all that much to the bottom line.
An alternate title was "House of the Rising Sun", clearly with emphasis on the rising sun reference to the Far East, rather than the usual bordello implication.
