"Once Upon a Time" season 3 will be premiering tonight on ABC at 8 p.m. ET.
Full episodes of the popular show are available to stream online on ABC, and tonight's premiere will be available tomorrow.
The synopsis for "Once Upon a Time" season 3 episode 1, titled "The Heart of the Truest Believer" is as follows: "Neverland to search for a kidnapped Henry, they're greeted by a school of not-to-friendly mermaids who threaten to end their search before it begins; Henry finds himself on the run from the Lost Boys with another escapee from Peter Pan's encampment; and Neal, recovering from his wounds, travels through the Enchanted Forest with Mulan in an attempt to learn the fates of Emma and Henry."
Expect to see the Charming Family, Robin Hood, Mermaids, and Captain Hook, who may be a potential love interest for Emma Swan.
The series will continue with the Charming family heading to Neverland to save Henry.
"Once Upon a Time" executive producer Edward Kitsis told TV writers last week: "The thing we wanted to do this year - we've always wanted to go to Neverland, but we really wanted to kind of focus on the core characters and we thought because Neverland is a place where you don't grow up, then you have to confront your past. Our inspiration was the idea that these characters would have to return to who they were before the curse in order to kind of achieve this. And at the same time, we wanted to have them dig deeper into what everything means. Last year, was such like a bullet and so we wanted to have time to kind of reflect on what's happened and what does it mean. Yeah, Emma looks at Mary Margaret as her mom, but does she really actually think of her as a mom?"
