The clock's ticking. Hamlin's selling wrapping paper out of the trunk of his car, and Dinah's going to leave him if he doesn't get his act together by Christmas Eve. While Dinah perfects her straight-razor shaves on her invalid brother, Jimmy, Hamlin blackmails the mysterious Lulu into helping him get his wife and life back. But Lulu quickly becomes the center of everyone's attention. And that's not a part of the plan. Tester is a world premiere by Jennifer Dobby, a Northwestern University Writing for the Screen + Stage MFA graduate and 2008-09 Dramatists Guild Fellow.
