Susan, a divorced mother, takes interest in Mike Delfino (James Denton), a plumber who has recently moved to Wisteria Lane; however, she faces competition with neighbor Edie Britt (Nicollette Sheridan), a promiscuous serial divorcée. Suspicious that Mike is spending the night with Edie, Susan enters Edie's home uninvited with the pretense of borrowing sugar. While inside, she accidentally knocks over a candle, which sets fire to the entire house. Susan flees the scene, leaving behind her glass measuring cup. Though wracked with guilt, Susan is relieved to learn that Mike was not the man with whom Edie was fornicating. Meanwhile, Lynette, a former career woman, is frustrated with raising four young children while her husband, Tom (Doug Savant), is constantly away on business.
