Worn out after his first night shift since returning to the ER, Carter (Noah Wyle) is summoned back to assist in Chen's (Ming-Na) delivery. Meanwhile, the people who want to adopt Chen's baby have reason to suspect that she'll renege on the agreement. Later, Abby (Maura Tierney) and Carter share their experiences with substance abuse after he toys with the notion of using a stimulant to stay awake. And in other developments, Greene (Anthony Edwards) is in New York, hoping to find someone that can treat his brain tumor; Kynesha (Toy Connor) continues hiding out from her would-be assassin with the help of Benton (Eriq La Salle) and Finch (Michael Michele); and Weaver (Laura Innes) is startled by a spontaneous act of affection -- from another woman.
