To find her missing brother, FBI agent Elena Cruz makes a dangerous deal with mafia heir Dante Moretti: she'll pose as his fiancée inside his family, and he'll help her search. There's one rule. His family can never learn she's a cop, because they kill cops, along with any man who protects one. Under Dante's roof, every family ritual tests her cover. His brother Nico is watching her, his father's chosen bride wants her gone, and her ex at the FBI is pushing her to send Dante to prison. The longer she plays his fiancée, the less she's pretending. When the family hunts for a traitor in their house, Elena has to decide how far she'll go for her brother, and how far Dante will go for her.
