Ex-SKUL conman Troy Greek is due to hand over some intel to MI9, but before MI9 can reach him, SKUL discover the plan and inject Greek with a deadly poison. Greek is now in a coma, awaiting the arrival of a vaccine and being kept alive by a machine.

When MI9 discover that a team of SKUL ninjas are out looking for Greek, they send him to the St Hope's base to ensure his protection. Frank agrees, thinking that the school will be empty as the kids are due to be away on a camping trip. Unfortunately, having failed to raise enough money to hire a coach Mr Flatley decides to relocate the camping trip - to the St Hope's gym! The spies reassure Frank that all will be ok - after all, the ninjas don't even know where the patient is hidden.

Carrie, exhausted and a little spooked from reading the latest Pookie Plummer horror novel, is initially unimpressed by Mr Flatley's attempts to recreate the great outdoors in St Hope's. However, when the lights go out and the ghost stories begin, Carrie soon finds herself feeling unnerved, and a run-in with the legendary Grey Lady of St Hope's pushes her over the edge. Terrified, Carrie tells Rose and Oscar about her ghostly encounter, but the team soon realise that the Grey Lady is in fact one of the SKUL Ninjas!

Realising that the ninjas are a threat not only to the patient but also to their classmates, the spies know they have to stop them. With Carrie feeling increasingly weighed down by her fears, can she battle her demons and prevent the ninjas from reaching the patient - and is the patient really all he seems? Show less
