Boomtown S02E02 - Inadmissible

David comes out of rehab and lands in the middle of the case against Sabrina and Donadoni, although not in the position he'd like at first; Ray and Katherine get bloodied on the witness stand at the preliminary hearing by Sabrina's attorney; David's struggle to stay sober is sorely tested when his father comes for a visit bearing extremely troubling news; when the diamonds stolen by Sabrina and Rachel can't be found, the task force puts their heads together with David to recover the gems, find the key to getting Sabrina to do a full flip on Donadoni, and put Donadoni behind bars.
