To get out of dinner with her parents, Susan tells her mom a little white lie---and gets caught in it.

Susan's plans for a picture-perfect anniversary party for her parents come screeching to a halt when she spies her dad having lunch with another woman, and kissing her in an extremely friendly fashion. Trying to duck her mother's questions about her father's unusual behavior, Susan is horrified when Liz inadvertently reveals that she is having an affair. Meanwhile, Jack's intimidating German squeeze, Kate, wants to hang out with Vicki - much to Vicki's dismay, since she's convinced Kate's appetite for danger will ultimately kill Jack, and perhaps some innocent bystanders as well.
