Now the Montecito has been sold to inexperienced young widow-heiress Monica Mancuso, who had it thoroughly renovated, Ed who stayed on as general manager is worried about the top-secret reopening, especially after two recent hold-ups in Indian casinos, but Monica refuses any delay so he can work in new staff. Most old key personnel has left. Danny now heads his late dad's contracting company McCoy Construction, but accepts to return as Ed's right hand, and rehires Mike -who was parking valet- and Sam, whose clients were deserting her, only Ed's daughter refuses.
