Danny William's (Scott Caan) upcoming romantic getaway with Amber (Lili Simmons) will definitely not go as planned, particularly after his girlfriend's ex drops by to win her back. While any date would suffer from the appearance of an old flame, Amber's former BF will put a violent spin on the tale of jilted lovers.

"Per usual, Danno's love life is going to get even more complicated when his girlfriend Amber's crazy, abusive ex-husband (David Hoflin) shows up hoping to win her back," teased Entertainment Weekly. "Let's just say things will get very violent and very bloody."
