'Once Upon A Time' Season 5 Episode 1 Live Stream Online: When, Where To Watch Premiere 'The Dark Swan' [VIDEO]

Tonight is the season five premiere of "Once Upon a Time" on ABC and we cannot contain our excitment! After the events in the season four finale, "Operation Mongoose," we are dying to know if our savior can truly fight off the dark ones essence or will she succumb to the power and be our new big bad.

In the fifth-season opener, Emma (Jennifer Morrison) seeks help from Merlin as she tries to fight her new dark urges in the Enchanted Forest, and she gets some assistance from Merida (Amy Manson), King Arthur (Liam Garrigan) and his knights. Meanwhile, Emma's loved ones unite and try to save her.

In a sneak peek clip we see Snow (Ginnifer Goodwin), Charming (Josh Dallas), Regina (Lana Parrilla), Robin (Sean Maguire), Hook (Colin O'Donoghue), Henry (Jared Gilmore), Belle (Emilie de Ravin) and Mother Superior (Keegan Connor Tracy) question the Apprentice about Emma's whereabouts. The Apprentice presents them with a wand that can help, but then dies. When Regina attempts to command the wand and fails, Hook suggests someone wicked. Check out the video below.
