The fourth season of the feminist-oriented doctor series Strong Medicine begins with an immediate followup to the previous season's cliffhanger ending. As the firefighter boyfriend of the Rittenhouse Clinic's director Dr. Lu Delgado (Rose Blasi) hovers between life and death after being shot by one of Lu's patients, Delgado's partner Dr. Andy Campbell (Patricia Richardson) makes the painful decision to separate from her abusive husband Les (Brian Kerwin), enraging her daughters Jessie (Michelle Horn) and Lizzie (Morgan Flynn) in the process. In later episodes, Andy begins a relationship with a Dr. Morton (Richard Biggs), but hesitates to introduce him to her daughters; Lu finds herself in a delicate situation when the man who raped her in Season Two comes back into her life--as a patient in desperate need of emergency heart surgery; the clinic's handsome-hunk male nurse Peter (John Coxx) unexpectedly lodges a protest when a chimpanzee is slated to be used for an experimental transplant procedure. Guest stars this season include Diahann Caroll,Shelly Long and Laila Ali, not to mention Grant Show, who in the season's concluding story arc makes three appearances as Ben Sanderson, a wealthy benefactor to the clinic. Because he is not open and above-board in his dealings, Ben incurs the rath of the combustible Lu. The tension reaches the breaking point in the season finale "Quarantine", in which an epidemic forces Lu and Ben to share some extremely close quarters--with astonishing results. ~ Hal Erickson, All Movie Guide
