Watch "Grimm" season 5 episode 4 live stream online via NBC streaming together with other NBC shows.

Season 5 will pose as a threat to the actors of "Grimm," according to a report by Youth Health Magazine.

According to the report, big plot and cast changes may be expected from the show and killing off characters may happen anytime soon.

David Giuntoli, who plays Nick Burkhardt in the series, revealed in an interview the fate of the current cast members.

"Season 5 is the closest thing we've had to a reboot," Giuntoli said. "Past characters are gone that you've come to love. The trailer is gone. You'll see soon that Nick's house goes. New sets, new plotlines, new enemies. There's a lot of creative juice to be wrung," added the "Grimm" cast member.

"I'll say this: No character is safe any longer," Giuntoli added. "We've been on for four years already, we can start shaking it up."

Meanwhile, a report from TV Guide revealed what fans should expect from the upcoming episode as a brief synopsis has been revealed and could be found below.

"A wealthy mobster sends three young men on a quest to win his daughter's hand in marriage and earn his fortune. Not too long after, Nick and Hank become involved in the case when bodies start to pile up. Meanwhile, Nick's home life is further disrupted by the arrival of a surprise visitor."
