Ally Undercover

On the outskirts of New York, an average family with average kids receive a visit from a surprise visitor...
Well, they find an unlikely visitor.
From the depths of the milky way, in a planet called Dreamtopia, an alien called Ally is sent to Earth for a mission. But when her cover is blown, she seeks help from her finders and finds a new identity. And this time, she's determined to succeed.
But when another disguised spy is sent, from Dreamtopia's rival planet, will Ally be able to eliminate him or will she fail her mission?
