Free LSD

Keith, an elderly sex shop owner, falls for a younger woman who visits his store looking for a gift. When their relationship turns physical, Keith's failure to perform leads him to a strange erectile dysfunction doctor who offers hope in the form of an experimental drug. It also provides a glimpse into a parallel universe where he is not only the singer of the band OFF!, but also the target of an advanced AI species that will stop at nothing to prevent the group from making a new album.
