After a fire ruins a neighborhood wedding, Boden steps up to host the ceremony at the firehouse. That's much to the chagrin of his boss, Chief Riddle, whose political aspirations have caused friction from within the firehouse. Meanwhile, Dawson, who returns to the house, also butts heads with Riddle over her ability to perform and is forced to defend herself despite Boden's support. Severide finds himself fighting for his way back to his old position and Capt. Patterson is caught between loyalty towards leadership and loyalty to his colleagues.
