Growing up, Susan Miller survived countless foster homes and years of abuse and neglect with one, burning goal: to someday find the birth mother who abandoned her - and get revenge.

On its last leg homeward, from Pearl Harbor, Hawaii to San Diego, the USS Constellation hosts a jolly "tiger cruise" for US Navy, Marines and USNAF relatives, mainly minors ("Navy brats").

Then the news of the WCC terror crisis changes everything, as the crew is recalled to war footing.
