Rocky is an amateur boxer, participating in mystery fights. He doesn't know who he will be up against. This time, it turns out to be Serena, an incredibly tall female bodybuilder, who intimidates him from the start. Serena looks down on him from on high. Her big muscles seem to be carved out of granite. Serena will play with Rocky a little, but otherwise will show no mercy, and will just enjoy using her incredible punching power on the smaller man.
