Deep below the sea surface works a legendary hero: Deep-sea Doctor Diederik. With his trusty submarine and a suitcase full of wonderful instruments, he cures every ailment that comes his way. No problem is too big, too strange, or too complicated for him. With humor, warmth, and ingenuity, he brings hope and recovery everywhere. Until one day his submarine suddenly breaks down… and the doctor himself faces his biggest challenge ever. An imaginative and heartwarming performance about caring for each other – and what happens when even a hero needs help. This theater performance is performed by the clients of Pegode, an organization that supports people with support needs.
