No, this is not a porn-parody, with name dropping early on of John Travolta and "Miami Vice" occasioned by star John Holmes wearing a spiffy white suit as close as it gets. Instead it's a soap opera from Patti Rhodes, hardly up to her quality work with husband Fred Lincoln.
Holmes likes to take his brother Joey Silvera and their pal Jim Harker out on the town on Saturday nights (hence the title), though this cheapie omits any scene of them visiting a night spot to pick up girls. We just see them bring the gals home for sex in bed or on the couch.
Harker lucks out humping Angel Kelly and Karen Summer in a threesome and later has a second sex scene with Caroline Connelly.
Soap opera plot has Silvera moping around after a break-up with fiancee, busty Vanessa D'Oro. Corny ending has them making up XXX style. Lousy script has such confusions as Vanessa's character named Angel, though Angel Kelly is in the cast without a character name.
Sex scenes are strictly routine.
