On a hot summer's day, the intrepid orange cat Tummy Tom discovers that his favourite soft toy has disappeared. Together with his friend Cat Mouse, he embarks on a search full of humour and surprises that takes him beyond the garden, into an unknown and fascinating world.

Based on the illustrated books by Jet Boeke, a classic of Dutch children's literature since 1978, Tummy Tom makes the leap to the big screen with hand-drawn animation that preserves the original lines and colours of the watercolours. An endearing story for little ones about friendship, curiosity and the value of small treasures.
