Morris and Banfield are snowed in and trapped at an ER conference in Nebraska. Back in Chicago, Alex and Sarah go behind Sam's back and get into a terrible car accident.

After Banfield defends herself from a street criminal, she and Dr. Gates treat a young gymnast with suspicious injuries indicating abuse. Dubenko's back on the surgery team.

Gates becomes obsessed with finding a homeless war hero; Neela's intern drags the entire surgery department into a lawsuit; things get physical when Brenner loses his cool with a patient.

Gates is stuck in a complicated living situation; Abby and Kovac consider hiring help as they juggle work and the new baby; Neela is disappointed when Dr. Crenshaw (J.P. Manoux) assigns menial jobs instead of surgical procedures.
