It's a relative thing. 

Siblings is a dark comedy about love, lust, murder and other issues of normal family life. When an odd group of step brothers and sisters (without blood relations of any kind) become orphaned by questionable circumstances, the loss of their despicably evil step parents should be the best thing that ever happened to them.

Of course, concealing the deaths, collecting an inheritance, and somehow sticking together as a family will prove to become an exceedingly complicated challenge. Growing up has its complications. Murder's just one of them.
