Gary Tank Commander (2009)

It's been 15 years since Gary's mum passed away and his dad Martin thinks that it's finally time to scatter her ashes. Gary, Martin, Julie and Gary's aunt Margaret all set out to his mum's favourite beauty spot, but find that it's changed a lot since they used to go there. Gary needs to come up with a back-up plan but he's distracted by a series of mysterious phone calls that not only annoy his aunt and Julie, but also manages to offend his dad on the worst day possible.
