The task of solving the grisly quadruple homicide of an entire family becomes more complicated when three people confess to the crime.

A sadistic killer from Sara's past who recently got out of prison appears to have struck again, while another dead body appears to have drowned in chocolate.

Goodman) would have been killed hadn't it been for a bullet proof tailored suit during the show by three shooters from different positions. Outside, a security guard's corpse is found, nose bullet-smashed. It looks like it least one presumed-dead mobster is actually alive and kills again, also on the run.
