Canadian-American activist "Paul Watson" is one of the world's most famous, and "infamous," environmentalists.  He's been arrested multiple times over his confrontations with whalers and seal hunters. Watson's latest activities have gotten him into trouble in Greenland, where he's been in jail for four months. Heidi Petracek reports on what's landed him behind bars, and whether he'll once again be able to find a way back onto the high seas.
