As the new Charmed One comes to terms with her powers, she finds herself resistant to accepting her destiny. Mel becomes protective and insistent on everyone embracing the new Power of Three, while Maggie is apathetic and aloof. But the girls must find a way to accept each other when a new threat starts tracking them.

When Maggie's demon-hunting leads her down a dangerous path, Mel decides it's time for them to take a break - and books the sisters for a weekend getaway. Meanwhile the new Charmed One is left in charge of the Command Center for the first time.. which doesn't go as well as anyone hopes.
