To find his missing parents, Bajo tries to hire a PI firm that deals with the unexplained. Turns out 'unexplained' means 'aliens' and PI means "Perpetually Incompetent".

It's Bajo's first day at SEPI and he is SO excited about working on an alien case. Turns out their first case is a missing cat, so that's a let down, but is something more sinister going on here? (Spoiler alert: yup.)

Our heroes are chasing an alien that can change itself to look like anyone. To crack the case Violet will have to hack an alien computer, Bajo will have to survive the speed-dating scene and Tosh will have to - make out with himself.

Surprise. Dan is in debt to a vicious alien mafia. And they want their money back, like, now. Now who is this lovely old lady at the door?

SEPI are hired to track down a stolen synthetic heart and the trail leads them deep into Tosh's sordid past: his old underground bike racing team. Along the way Bajo makes a strange new friend.

SEPI are tracking the last dinosaur for a conservation group. And if you were wondering how long it could take for our heroes to visit the jungle, get really lost, and turn on each other, the answer is about 3 minutes.

Cor Blimey. A robotic arm has gone rogue and become the latest online video sensation. Can Tosh's bizarre past in the underground handshake scene save the day? Will Bajo's terrible undercover accent help anything?

How will SEPI pay the rent without some stinky, old eggs? They've gone missing. But the scent has not. It smells like an inside job - so Violet can FINALLY investigate a mystery...What could possibly go wrong with Violet on the case?

After Bajo's parents went missing in a burrito truck, the first place Bajo should've checked is an ice cream van. Obviously. Bizarre Illack Ursula may know something about the disappearance of Bajo's parents, but she's not super keen on helping.

Desperate for cash to pay the bills, the SEPI team take on a case with no aliens. Instead they go undercover to investigate a love cheat. Oh yes, SEPI knows how to investigate sensitive situations like that.

Dan has been kidnapped by the Needlers. If Bajo is going to save his boss he is going to have to wade into a sinister trap that involves a vicious alien bird, hacking ancient computers and several cups of delicious tea.

When SEPI are hired to protect famous pop star Lola from a kidnapping plot they take her to a rickety old safe house. Who would have thought it would be so hard to keep a safe house, you know, safe?

Man, our heroes have been working hard recently, but luckily their next mission is at a super relaxing health spa - It's a pity that the spa is neither super, relaxing, nor particularly healthy.

Ugh, you know those days where you have to take on a cult leader for possession of an intergalactic mail pod and you wind up trapped in his bizarre alien worship cult and you can't get out? This is one of those days.

Violet is in a coma. Luckily Bajo knows what every first-aider knows: to get someone out of a coma you convince them to wake up by travelling into their subconscious using homemade virtual reality gear.

Our heroes are hired to get rid of a dangerous alien monster, but the mission parameters change pretty quickly from 'solve the case' to 'maybe just not dying would be great'.

It's time for the epic season finale. Will the team save Lola and stay out of jail? Will Bajo finally find out what happened to his parents? And most importantly, will Tosh become an actual ninja?
