Spiders and broken legs

Two mischievous identical (if you don't count their gender) twins, Tony - whose the eldest by 10.245 seconds to be exact - and Tori are recruited into a secret agency MI3 because their beloved dad, who is actually a top MI3 'adults devision' agent dies in an apparently accidental car crash throwing him and his high tech car into the ocean while the twins were on the bus to school. He prepared them their whole life for what's about to come but they need to prepare much more before they will be ready for their first lifethreating undercover mission or will they even except the offer to be a spy after what it did to her parents?
