Personally, I'd do two light days. A super light one on wednesday, and a bit heavier one on saturday. Saturday and Wednesday would be better, between saturday and monday you have one day of rest, and between wednesday and saturday you have two days of rest. Just take it easy if you're starting on plyos, if anything starts to hurt, I'd back off right away. I hope this is good advice, if Mike or d3 have a different opinion, I'd value theirs over mine.
