Tomorrow there will be sun

Two families arrive in Puerto Vallarta Mexico for a once-in-a-lifetime vacation. Jenna has organized the trip to celebrate her husband's fiftieth birthday--she's been looking forward to it for months. She's sure everything is going to be just perfect--and the margarita refills delivered by the house staff certainly don't hurt either. What could go wrong? Yet as the families settle into their vacation routines their best friends suddenly seem like annoying strangers and even Jenna's reliable husband Peter is sharing clandestine phone calls with someone--but who? Jenna's teenage daughter Clem is spending an awful lot of time with Malcolm whose questionable rep got him expelled from school. Jenna's dream of the ultimate celebration begins to crack and eventually crumbles completely leaving her wondering whom she can trust and whether her privileged life is about to be changed forever.
